In computing, TIME is a command in DEC RT-11, DOS, IBM OS/2, Microsoft Windows and a number of other operating systems that is used to display and set the current system time. It is included in command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS, 4OS2 and 4NT.

Implementations

Description of the TIME command of RT-11SJ displayed on a VT100.

The command is also available in the Motorola VERSAdos, Intel iRMX 86, PC-MOS, SpartaDOS X, ReactOS, SymbOS, and DexOS operating systems as well as in the EFI shell. On MS-DOS, the command is available in versions 1 and later.

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.

OS/2 (CMD.EXE)

Note: /N means no prompt for TIME.

Windows (CMD.EXE)

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.

4DOS, 4OS2 and 4NT
