Implementations
TIME command of RT-11SJ displayed on a VT100.The command is also available in the Motorola VERSAdos,[5] Intel iRMX 86,[6] PC-MOS,[7] SpartaDOS X,[8] ReactOS,[9] SymbOS, and DexOS operating systems as well as in the EFI shell.[10] On MS-DOS, the command is available in versions 1 and later.[11]
In Unix, the date command displays and sets both the time and date, in a similar manner.
Syntax
The syntax differs depending on the specific platform and implementation:
DOS
TIME.COM (among other commands) in IBM PC DOS 1.0.TIME [time]
OS/2 (CMD.EXE)
TIME [hh-mm-ss] [/N]
Note: /N means no prompt for TIME.
Windows (CMD.EXE)
TIME [/T | time]
When this command is called from the command line or a batch script, it will display the time and wait for the user to type a new time and press RETURN. Pressing RETURN without entering a new time will keep the current system time. The parameter '/T' will bypass asking the user to reset the time. The '/T' parameter is supported in Windows Vista and later and only if Command Extensions are enabled.[4]
4DOS, 4OS2 and 4NT
TIME [/T] [hh[:mm[:ss]]] [AM | PM]
/T: (display only)
hh: The hour (0–23).
mm: The minute (0–59).
ss: The second (0–59), set to 0 if omitted.
Examples
OS/2 (CMD.EXE)
- Display the current system time:
[C:\]TIME

Windows (CMD.EXE)
- To set the computer clock to 3:42 P.M., either of the following commands can be used:
C:\>TIME 15:42
C:\>TIME 3:42P
4DOS, 4OS2 and 4NT
- Display the current system time:
C:\SYS\SHELL\4DOS>TIME /T

The command can be used to convert an NTTE or NTP formatted date into a readable format.[14]
As an example of using the command, the current time zone settings can be displayed using the /tz parameter:
