If you don't need to know the logon time of user, even if they are logged off, but only need the logon date and time of the current logged on user, use LogonTime.bat.

The syntax for using LogonTime.bat is:

\[call\] LogonTime LT

Where LT is a call directed environment variable that will contain the date and time of the current user's logon, like MM/DD/YYYY HH:MM:SS.

NOTE: LogonTime.bat uses LogonSessions.exe, which should be located in a folder that is in your PATH, or in the same folder as LogonTime.bat.

LogonTime.bat contains:
