How to get PC uptime in batch? - batch-file

Question

I have a script here that will give me an uptime but it is not the correct up time and I dont really know where the error is or if this is even the best way to do it but it is what I have. End game I want to set the uptime to a variable and if greater than x I will do a reboot or promt the user for a reboot and I will put this script in under the task scheduler. Either way here is what I have. Hope it is sufficient enough and I dont get scaled too bad over a stupid question.
#echo off
setlocal ENABLEEXTENSIONS
call :Uptime d h n s
echo/Uptime is: %d% days, %h% hours, %n% minutes, %s% seconds.
pause
goto :EOF

Try a batch file leveraging powershell.
#Echo Off&SetLocal
For /F "UseBackQ Tokens=1-4" %%A In (
`Powershell "$OS=GWmi Win32_OperatingSystem;$UP=(Get-Date)-"^
"($OS.ConvertToDateTime($OS.LastBootUpTime));$DO='d='+$UP.Days+"^
"' h='+$UP.Hours+' n='+$UP.Minutes+' s='+$UP.Seconds;Echo $DO"`) Do (
Set "%%A"&Set "%%B"&Set "%%C"&Set "%%D")
Echo(Uptime is: %d% days, %h% hours, %n% minutes, %s% seconds.
