Batch: Timestamp to UNIX Time

For all I know, Batch does not have a command that gives the UNIX time. The closest one I can find is %time%, which only displays the timestamp.

Is there a command, or set of commands in Batch with which you can get the UNIX time?

There's Richie Lawrence's batch library that has all those nifty handy scripts. The one you need is DateToSec (which uses GetDate and GetTime).\n\nHere's a simplified script, that employs a little WMI:\n\n@echo off\nsetlocal\ncall :GetUnixTime UNIX_TIME\necho %UNIX_TIME% seconds have elapsed since 1970-01-01 00:00:00\ngoto :EOF\n\n:GetUnixTime\nsetlocal enableextensions\nfor /f %%x in ('wmic path win32_utctime get /format:list ^| findstr \"=\"') do (\n set %%x)\nset /a z=(14-100%Month%%%100)/12, y=10000%Year%%%10000-z\nset /a ut=y*365+y/4-y/100+y/400+(153*(100%Month%%%100+12*z-3)+2)/5+Day-719469\nset /a ut=ut*86400+100%Hour%%%100*3600+100%Minute%%%100*60+100%Second%%%100\nendlocal & set \"%1=%ut%\" & goto :EOF\n\n\nThe result will be returned into the first parameter passed to GetUnixTime, i.e. %UNIX_TIME%.\nFor example:\n\n1341791426 seconds have elapsed since 1970-01-01 00:00:00\n\n\nHope it helps!",

create a .bat file called \"getUtime.bat\"\n\n@echo off\necho WScript.Echo(new Date().getTime()); > %temp%\\time.js\ncscript //nologo %temp%\\time.js\ndel %temp%\\time.js\n\n\nand call like this \n\n\"C:\\>getUTime\"\n1430894237616\n",

What about simple 1-line long C program returning UNIX timestamp? You can retrieve value from %errorlevel% in batch script.\n\n#include <stdio.h>\n#include <time.h>\n\nint main(void)\n{\n return (int) time(NULL);\n}\n\n\nIn my test in command prompt it worked:\n\nC:\\Users\\dabaran\\Desktop\\cs50\\src\\C>.\\time || echo %errorlevel% && set mytstamp=%errorlevel%\n1419609373\n\nC:\\Users\\dabaran\\Desktop\\cs50\\src\\C>echo %mytstamp%\n1419609373\n",

There's a really simple way of doing this in a single batch file with no external scripts, files, libraries, etc.\n\n\n<job><script language="JavaScript">\n WScript.Echo(new Date().getTime());\n</script></job>\n\nThe way it works is, code for a batch script AND code for a JS file are contained in the same .cmd or .bat file. you can force cscript to run the batch file as a script by commenting out the batch code and the : after the first line means batch will ignore it and run the batch code directly. so there you go!",

There is no batch command for returning UNIX time. Your only options would be to write a program which could be run from a batch file that would return the UNIX time, or you could use the Windows PowerShell.",
