Converting Milliseconds to Minutes and Seconds in momentjs - reactjs

1.from: 2380 //time in milliseconds to minutes and seconds
example:
2380 is 0.2 sec convert to 00:02 (min:sec)
var fromDuration = moment.duration(from, 'milliseconds');
var fromMinutes = Math.ceil(fromDuration.asMinutes());
var fromSeconds = Math.ceil(fromDuration.asSeconds());


My solution is:
const millisecondsToMinutesSeconds = (ms) => {
let duration = moment.duration(ms, 'milliseconds');
let fromMinutes = Math.floor(duration.asMinutes());
let fromSeconds = Math.floor(duration.asSeconds() - fromMinutes * 60);
return Math.floor(duration.asSeconds()) >= 60 ? (fromMinutes<= 9 ? '0'+fromMinutes : fromMinutes) +':'+ (fromSeconds<= 9 ? '0'+fromSeconds : fromSeconds)
: '00:'+(fromSeconds<= 9 ? '0'+fromSeconds : fromSeconds);
};

Converting unix time to date time [duplicate]

I am storing time in a MySQL database as a Unix timestamp and that gets sent to some JavaScript code. How would I get just the time out of it?
For example, in HH/MM/SS format.

let unix_timestamp = 1549312452
// Create a new JavaScript Date object based on the timestamp
// multiplied by 1000 so that the argument is in milliseconds, not seconds.
var date = new Date(unix_timestamp * 1000);
// Hours part from the timestamp
var hours = date.getHours();
// Minutes part from the timestamp
var minutes = "0" + date.getMinutes();
// Seconds part from the timestamp
var seconds = "0" + date.getSeconds();
// Will display time in 10:30:23 format
var formattedTime = hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);
console.log(formattedTime);
For more information regarding the Date object, please refer to MDN or the ECMAScript 5 specification.

function timeConverter(UNIX_timestamp){
var a = new Date(UNIX_timestamp * 1000);
var months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
var year = a.getFullYear();
var month = months[a.getMonth()];
var date = a.getDate();
var hour = a.getHours();
var min = a.getMinutes();
var sec = a.getSeconds();
var time = date + ' ' + month + ' ' + year + ' ' + hour + ':' + min + ':' + sec ;
return time;
}
console.log(timeConverter(0));

JavaScript works in milliseconds, so you'll first have to convert the UNIX timestamp from seconds to milliseconds.
var date = new Date(UNIX_Timestamp * 1000);
// Manipulate JavaScript Date object here...

Use:
var s = new Date(1504095567183).toLocaleDateString("en-US")
console.log(s)
// expected output "8/30/2017"
and for time:
var s = new Date(1504095567183).toLocaleTimeString("en-US")
console.log(s)
// expected output "3:19:27 PM"
see Date.prototype.toLocaleDateString()

Modern Solution (for 2020)
In the new world, we should be moving towards the standard Intl JavaScript object, that has a handy DateTimeFormat constructor with .format() method:
function format_time(s) {
const dtFormat = new Intl.DateTimeFormat('en-GB', {
timeStyle: 'medium',
timeZone: 'UTC'
});
return dtFormat.format(new Date(s * 1e3));
}
console.log( format_time(12345) ); // "03:25:45"
Eternal Solution
But to be 100% compatible with all legacy JavaScript engines, here is the shortest one-liner solution to format seconds as hh:mm:ss:
function format_time(s) {
return new Date(s * 1e3).toISOString().slice(-13, -5);
}
console.log( format_time(12345) ); // "03:25:45"
Method Date.prototype.toISOString() returns time in
simplified extended ISO 8601 format, which is always 24 or 27 characters long (i.e. YYYY-MM-DDTHH:mm:ss.sssZ or
±YYYYYY-MM-DDTHH:mm:ss.sssZ respectively). The timezone is always
zero UTC offset.
This solution does not require any third-party libraries and is supported in all browsers and JavaScript engines.

I'm partial to Jacob Wright's Date.format() library, which implements JavaScript date formatting in the style of PHP's date() function.
new Date(unix_timestamp * 1000).format('h:i:s')

I'd think about using a library like momentjs.com, that makes this really simple:
Based on a Unix timestamp:
var timestamp = moment.unix(1293683278);
console.log( timestamp.format("HH/mm/ss") );
Based on a MySQL date string:
var now = moment("2010-10-10 12:03:15");
console.log( now.format("HH/mm/ss") );

shortest one-liner solution to format seconds as hh:mm:ss: variant:
console.log(new Date(1549312452 * 1000).toISOString().slice(0, 19).replace('T', ' '));
// "2019-02-04 20:34:12"

In moment you must use unix timestamp:
const dateTimeString = moment.unix(1466760005).format("DD-MM-YYYY HH:mm:ss");

This works with PHP timestamps
var d = 1541415288860;
//var d =val.timestamp;
//NB: use + before variable name
var date = new Date(+d);
console.log(d);
console.log(date.toDateString());
console.log(date.getFullYear());
console.log(date.getMinutes());
console.log(date.getSeconds());
console.log(date.getHours());
console.log(date.toLocaleTimeString());
var d =val.timestamp;
var date=new Date(+d); //NB: use + before variable name
console.log(d);
console.log(date.toDateString());
console.log(date.getFullYear());
console.log(date.getMinutes());
console.log(date.getSeconds());
console.log(date.getHours());
console.log(date.toLocaleTimeString());
the methods above will generate this results

There's a bunch of methods that work perfectly with timestamps. Cant list them all

UNIX timestamp is number of seconds since 00:00:00 UTC on January 1, 1970 (according to Wikipedia).
Argument of Date object in Javascript is number of miliseconds since 00:00:00 UTC on January 1, 1970 (according to W3Schools Javascript documentation).
See code below for example:
function tm(unix_tm) {
var dt = new Date(unix_tm*1000);
document.writeln(dt.getHours() + '/' + dt.getMinutes() + '/' + dt.getSeconds() + ' -- ' + dt + '<br>');
}
tm(60);
tm(86400);
gives:
1/1/0 -- Thu Jan 01 1970 01:01:00 GMT+0100 (Central European Standard Time)
1/0/0 -- Fri Jan 02 1970 01:00:00 GMT+0100 (Central European Standard Time)

Using Moment.js, you can get time and date like this:
var dateTimeString = moment(1439198499).format("DD-MM-YYYY HH:mm:ss");
And you can get only time using this:
var timeString = moment(1439198499).format("HH:mm:ss");

The problem with the aforementioned solutions is, that if hour, minute or second, has only one digit (i.e. 0-9), the time would be wrong, e.g. it could be 2:3:9, but it should rather be 02:03:09.
According to this page it seems to be a better solution to use Date's "toLocaleTimeString" method.

Another way - from an ISO 8601 date.
var timestamp = 1293683278;
var date = new Date(timestamp * 1000);
var iso = date.toISOString().match(/(\d{2}:\d{2}:\d{2})/)
alert(iso[1]);

Based on #shomrat's answer, here is a snippet that automatically writes datetime like this (a bit similar to StackOverflow's date for answers: answered Nov 6 '16 at 11:51):
today, 11:23
or
yersterday, 11:23
or (if different but same year than today)
6 Nov, 11:23
or (if another year than today)
6 Nov 2016, 11:23
function timeConverter(t) {
var a = new Date(t * 1000);
var today = new Date();
var yesterday = new Date(Date.now() - 86400000);
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
var year = a.getFullYear();
var month = months[a.getMonth()];
var date = a.getDate();
var hour = a.getHours();
var min = a.getMinutes();
if (a.setHours(0,0,0,0) == today.setHours(0,0,0,0))
return 'today, ' + hour + ':' + min;
else if (a.setHours(0,0,0,0) == yesterday.setHours(0,0,0,0))
return 'yesterday, ' + hour + ':' + min;
else if (year == today.getFullYear())
return date + ' ' + month + ', ' + hour + ':' + min;
else
return date + ' ' + month + ' ' + year + ', ' + hour + ':' + min;
}

function getTIMESTAMP() {
var date = new Date();
var year = date.getFullYear();
var month = ("0" + (date.getMonth() + 1)).substr(-2);
var day = ("0" + date.getDate()).substr(-2);
var hour = ("0" + date.getHours()).substr(-2);
var minutes = ("0" + date.getMinutes()).substr(-2);
var seconds = ("0" + date.getSeconds()).substr(-2);
return year + "-" + month + "-" + day + " " + hour + ":" + minutes + ":" + seconds;
}
//2016-01-14 02:40:01

The modern solution that doesn't need a 40 KB library:
Intl.DateTimeFormat is the non-culturally imperialistic way to format a date/time.
// Setup once
var options = {
//weekday: 'long',
//month: 'short',
//year: 'numeric',
//day: 'numeric',
hour: 'numeric',
minute: 'numeric',
second: 'numeric'
},
intlDate = new Intl.DateTimeFormat( undefined, options );
// Reusable formatter
var timeStamp = 1412743273;
console.log( intlDate.format( new Date( 1000 * timeStamp ) ) );

Pay attention to the zero problem with some of the answers. For example, the timestamp 1439329773 would be mistakenly converted to 12/08/2015 0:49.
I would suggest on using the following to overcome this issue:
var timestamp = 1439329773; // replace your timestamp
var date = new Date(timestamp * 1000);
var formattedDate = ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
console.log(formattedDate);
Now results in:
12/08/2015 00:49

There are multiple ways to convert unix timestamp to time (HH/MM/SS)
Using new Date() - this is in-built in javascript
moment package - this is a famous node module, but this is going to deprecate.
dayjs package - this is one of the latest and fast growing node module
Using new Date()
const dateTimeStr = new Date(1504052527183).toLocaleString()
const result = (dateTimeStr.split(", ")[1]).split(":").join("/")
console.log(result)
Using moment
const moment = require('moment')
const timestampObj = moment.unix(1504052527183);
const result = timestampObj.format("HH/mm/ss")
console.log(result);
Using day.js
const dayjs = require('dayjs')
const result = dayjs(1504052527183).format("HH/mm/ss")
console.log(result);
you can check the timestamp to time conversion with an online time conversion tool

// Format value as two digits 0 => 00, 1 => 01
function twoDigits(value) {
if(value < 10) {
return '0' + value;
}
return value;
}
var date = new Date(unix_timestamp*1000);
// display in format HH:MM:SS
var formattedTime = twoDigits(date.getHours())
+ ':' + twoDigits(date.getMinutes())
+ ':' + twoDigits(date.getSeconds());

function getDateTimeFromTimestamp(unixTimeStamp) {
let date = new Date(unixTimeStamp);
return ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
}
const myTime = getDateTimeFromTimestamp(1435986900000);
console.log(myTime); // output 01/05/2000 11:00

You can use the following function to convert your timestamp to HH:MM:SS format :
var convertTime = function(timestamp, separator) {
var pad = function(input) {return input < 10 ? "0" + input : input;};
var date = timestamp ? new Date(timestamp * 1000) : new Date();
return [
pad(date.getHours()),
pad(date.getMinutes()),
pad(date.getSeconds())
].join(typeof separator !== 'undefined' ? separator : ':' );
}
Without passing a separator, it uses : as the (default) separator :
time = convertTime(1061351153); // --> OUTPUT = 05:45:53
If you want to use / as a separator, just pass it as the second parameter:
time = convertTime(920535115, '/'); // --> OUTPUT = 09/11/55
Demo
var convertTime = function(timestamp, separator) {
var pad = function(input) {return input < 10 ? "0" + input : input;};
var date = timestamp ? new Date(timestamp * 1000) : new Date();
return [
pad(date.getHours()),
pad(date.getMinutes()),
pad(date.getSeconds())
].join(typeof separator !== 'undefined' ? separator : ':' );
}
document.body.innerHTML = '<pre>' + JSON.stringify({
920535115 : convertTime(920535115, '/'),
1061351153 : convertTime(1061351153, ':'),
1435651350 : convertTime(1435651350, '-'),
1487938926 : convertTime(1487938926),
1555135551 : convertTime(1555135551, '.')
}, null, '\t') + '</pre>';

See Date/Epoch Converter.
You need to ParseInt, otherwise it wouldn't work:
if (!window.a)
window.a = new Date();
var mEpoch = parseInt(UNIX_timestamp);
if (mEpoch < 10000000000)
mEpoch *= 1000;

a.setTime(mEpoch);

If you want to convert Unix time duration to real hours, minutes, and seconds, you could use the following code:
var hours = Math.floor(timestamp / 60 / 60);
var minutes = Math.floor((timestamp - hours * 60 * 60) / 60);
var seconds = Math.floor(timestamp - hours * 60 * 60 - minutes * 60 );
var duration = hours + ':' + minutes + ':' + seconds;

Code below also provides 3-digit millisecs, ideal for console log prefixes:
const timeStrGet = date => {
const milliSecsStr = date.getMilliseconds().toString().padStart(3, '0') ;
return `${date.toLocaleTimeString('it-US')}.${milliSecsStr}`;
};
setInterval(() => console.log(timeStrGet(new Date())), 299);

Angularjs split last hour in 10 minutes slices

Is there a way I can take the time between now and last hour and split it in 10 minutes slices in AngularJS? Something like below
10:00:00
09:50:00
09:40:00
09:30:00
09:20:00
09:10:00
09:00:00
The start time code is
//time now -1 hour
$scope.startTime = new Date( (new Date) * 1 - 1000 * 3600 * 1 );
And for end time I am using
//time now
$scope.endTime = new Date();
To make it a genuine date I am using this function
Date.prototype.yyyymmddhhmm = function() {
var yyyy = this.getFullYear();
var mm = this.getMonth() < 9 ? "0" + (this.getMonth() + 1) : (this.getMonth() + 1); // getMonth() is zero-based
var dd = this.getDate() < 10 ? "0" + this.getDate() : this.getDate();
var hh = this.getHours() < 10 ? "0" + this.getHours() : this.getHours();
var min = this.getMinutes() < 10 ? "0" + this.getMinutes() : this.getMinutes();
var sec = this.getSeconds() < 10 ? "0" + this.getSeconds() : this.getSeconds();
return "".concat(yyyy + '-').concat(mm + '-').concat(dd + ' ').concat(hh + ':').concat(min + ':').concat(sec);
};
What I need the 10 minutes slices is for a Line Chart labels.

var startTime = new Date( endTime.getTime() - 1000 * 3600 );
var time = startTime;
while (time < endTime) {
time = new Date(time.getTime() + 1000 * 60 * 10);
// do something with the generated time
}
This doesn't use anything you didn't already use, I'm confused as to what you got stuck on.

how can i set time in angularjs as [ 2 min ago ] if [difference is 2 min from current time]?

I am trying to set a time as for example , i have time as [ 01:25:00 ] then if now current time is [ 01:28:00 ] . It should show as "3 min ago". how can i do using angular and ionic.
i am trying some thing like :
1 min ago , 2 min ago , 30 min ago , 1 hour ago
my html code:
<div class="item item-divider item-input-wrapper">
<p>Time : {{ messages.MSGTIME | date:'shortTime'}} </p>
</div>
Thanks in advance

If you don't want to use moment.js (what I would recommend) you can write your own date filter. A simple example (http://plnkr.co/edit/BVH5Q3?p=preview):
angular.module('app').filter('myDate', myDate);
function myDate() {
var s = 1000;
var m = s * 60;
var h = m * 60;
return function(date) {
var d = date.getTime() - Date.now();
if (d > h)
return '' + d / h + ' hours ago';
if (d > m)
return '' + d / m + ' minutes ago';
if (d > s)
return '' + d / s + ' seconds ago';
return '' + d + ' ms ago';;
}
}

Use angular-moment , filter amDifference can fullfill your purpose. You cna use it like this :
<p>Time : {{ messages.MSGTIME | amDifference : null : 'hours'}} </p>

I'm in a hurry right now, but here something from the top of my head for a q'n'd approach:
Create own filter
split(":") both time strings
calc difference of hours and minutes
then:
ret = (diffHours > 0)? diffHours + " hours and " : "";
ret += diffMinutes + " minutes ago";
return ret;
