TIME (command)
Command used to display and set time

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.
01Implementations
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.

02Syntax
The syntax differs depending on the specific platform and implementation:
DOS
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.
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.03Examples
