I want to set a Windows environment variable from the results of TIME /t.

In Windows, the %time% variable yields one format (13:17:52.79), whereas TIME /t has another (01:17 PM).

I've tried sending it to a text file and trying to append "SET xxx=" but there is always a line feed that I cannot seem to eliminate.

For example, I can "ECHO Set xxx= >> TTT.txt" and "TIME /t >> TTT.txt" but the results are on two separate lines. The same is true when I make two files and try to COPY /b. I have also experimented with similar methods using WMIC.

Any ideas?

In cmd.exe, for /f can be used to read command output:

for /f %%a in ('time /t') do set xxx=%%a

See for /? for more details.

  • Thanks! Almost there! It misses the AM/PM. I assume that's because there is a space in the output between the numbers and the AM/PM. I read the /? for the "FOR" command and tried a few variations but no luck yet. – Southern Builder Aug 1 '18 at 21:01
  • Ah, use "tokens=*" to catch multiple words. – user1686 Aug 1 '18 at 21:27
  • That does it! Thank you so much! I've been fighting this for so long! – Southern Builder Aug 1 '18 at 21:48
