I have a table that stores the transaction date time in UTC time zone. I would need to convert this time to eastern time zone i.e. EST or EDT, depending on the transaction date.
How can I do this without writing a big function or creating a table / view that flags EST / EDT for each transaction date?
Use AT TIME ZONE, which changes the timezone of a value to the relevant time there, and observes Daylight Saving:
SELECT CONVERT(datetimeoffset(0),'2021-09-07T15:25:37+00:00') AT TIME ZONE 'Eastern Standard Time' AS Sep21,
CONVERT(datetimeoffset(0),'2021-01-09T15:25:37+00:00') AT TIME ZONE 'Eastern Standard Time' AS Jan21;
Which returns the following:
Sep21 Jan21
---------------------------------- ----------------------------------
2021-09-07 11:25:37 -04:00 2021-01-09 10:25:37 -05:00

I have a database that records time in UTC. I need to convert this time to Local Time, and then aggregate the data by Month on this new Local Time that I have created. Everything works fine if I just aggregate on the original UTC Time, but of course, the value that I get at the end is slightly off which does not work for me. However, if I try to aggregate on Local Time, I just can't get it to work.
I am unable to use TIMESTAMP_LOCAL in my GROUP BY Clause, and neither am I able to use the whole YEAR(CONVERT(DATETIME2(3), TIMESTAMP_UTC AT TIME ZONE 'UTC' AT TIME ZONE 'Central European Standard Time'). Same goes for the entire DATEFROMPARTS Function.
SELECT
SUM([VALUE]) AS Required_Value
,DATEFROMPARTS(YEAR(CONVERT(DATETIME2(3), TIMESTAMP_UTC AT TIME ZONE 'UTC' AT TIME ZONE 'Central European Standard Time')), MONTH(CONVERT(DATETIME2(3), TIMESTAMP_UTC AT TIME ZONE 'UTC' AT TIME ZONE 'Central European Standard Time')), 1) AS TIMESTAMP_LOCAL
FROM [DB].[TABLE]
GROUP BY ???
I'm sending an email and I want to get the time when a file is uploaded, but the default time is in UTC.
I tried several things to convert from UTC to Central Time for example. Is there any expression to convert from UTC in Azure Logic Apps?
I tried the following expression:
convertTimeZone('HH:mm:ss', 'UTC', 'Pacific Standard Time')
As suggested by Timothy Radier , you can use combination of both formatDateTime ,convertTimeZone expression to covert the UTC time zone to Central standard time zone.
formatDateTime(convertTimeZone(utcNow(), 'UTC', 'Central Standard Time'),'HH:mm:ss')
Alternatively , By default central time zone is 5 hours behind the utc time you can also use 'subtractFromTime' expression to convert utc time to central time.
formatDateTime(subtractFromTime(utcNow(),5,'Hour'),'HH:mm:ss')
Here is the reference output :
The below SQL will convert the UTC time to my local time in BRISBANE, Australia.
I would like to get the Local time in Sydney which is 1 hour ahead of Brisbane time considering the DST
SELECT
GETUTCDATE() AS UTCTime,
CAST(GETUTCDATE() AT TIME ZONE 'UTC' AT TIME ZONE 'E. Australia Standard Time' AS DATETIME2(2)) AS BrisbaneTime
Need some assistance in getting the local time in Sydney.
All of the possible timezones are defined in the sys.time_zone_info system table. From there you can select the appropriate timeone to use.
You would use the same query but with the other timezone
I am using SQL Server 2014
Currently, I am using MSSQL function:
format(TODATETIMEOFFSET(("[dateColumn]",'-6:00'),'MM/dd/yyyy')
However, this will not apply Daylight savings.
How can i achieve it?
Please help
This answer was provided before information was received that the OP was using SQL Server 2014 (which I have now added to their tags). I have left the answer here, however, as it will likely be helpful for future readers using a more recent version of SQL Server.
UTC -6 will always be UTC -6; it doesn't change for daylight savings and become UTC -5. Timezones like GMT (UTC+0) and EST (UTC-5) change to BST and EDT but then they also respectively become UTC +1 AND UTC -4. You're providing a literal number so the value will always be UTC -6.
What you are likely looking for is AT TIME ZONE (AT TIME ZONE (Transact-SQL), which was introduced with SQL Server 2016. For example:
--Returns 2018-01-01 18:00:00 -06:00
SELECT CONVERT(datetime2(0), '2018-01-01T18:00:00') AT TIME ZONE 'Central Standard Time';
--Returns 2018-07-01 18:00:00 -05:00 (changes to -5, due to daylight saving)
SELECT CONVERT(datetime2(0), '2018-07-01T18:00:00') AT TIME ZONE 'Central Standard Time';
I'm trying to display datetime values in local time. By default, Azure SQL Database stores dates and times in UTC, there is no way around this. (This was a pain when migrating from on premise SQL Server.) I would like to display a stored time value in Central European time.
Now the local time is 11:30 (CET). UTC time is 10:30.
DECLARE #TestTime DATETIME;
SET #TestTime = '2016-11-02 10:30:00'
SELECT #TestTime
--Returns 2016-11-02 10:30:00
SELECT #TestTime AT TIME ZONE 'Central European Standard Time'
--Returns 02 November 2016 10:30:00 +01:00
I need to return 2016-11-02 11:30:00 somehow. Now for the fun part:
As has been suggested here:
SELECT convert(DATETIME,#TestTime AT TIME ZONE 'Central European Standard Time',1)
--Returns 2016-11-02 09:30:00 So instead of adding the timezonedifference it subtracts it.
This works, but makes me sick:
SELECT DATEADD(MINUTE,DATEPART(tz,#TestTime AT TIME ZONE 'Central European Standard Time'),#TestTime)
--Returns 2016-11-02 11:30:00
A similar solution has been suggested here, but it plays with string operations. My suspicion is that something is wrong in AT TIME ZONE; it should have displayed 11:30 +1, and not 10:30 +1, no?
Is there really no proper way to display a UTC time in local time? This "hacking around it" feels awfully dirty, especially since at any point in time it just might stop working (e.g. Microsoft fixes / introduces a bug).
Thanks!
The AT TIME ZONE statement performs two distinct operations:
To assert that a datetime (or datetime2) is in a particular time zone, thus looking up the correct offset for that zone and returning a datetimeoffset value with the correct offset applied.
To convert a datetimeoffset value to a different time zone, using the offset from the source value to pin down an exact point in time, then looking up the new offset for the requested time zone and applying it. This returns a datetimeoffset with a potentially different local time and offset than the original, but representing the same moment in time.
You are using the first part only. To convert a datetime from UTC to a specific time zone, you'll need to use both.
SELECT #TestTime AT TIME ZONE 'UTC' AT TIME ZONE 'Central European Standard Time'
The first AT TIME ZONE asserts that the input datetime is in UTC, resulting in a datetimeoffset that has +00:00 for the offset. The second AT TIME ZONE converts that to the time zone requested.
