In computing, TIME is a command in DEC RT-11,[1] DOS, IBM OS/2,[2] Microsoft Windows[3] and a number of other operating systems that is used to display and set the current system time.[4] It is included in command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS, 4OS2 and 4NT.
Implementations
[edit]
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
[edit]The syntax differs depending on the specific platform and implementation:
DOS
[edit]
TIME.COM (among other commands) in IBM PC DOS 1.0.TIME [time]
OS/2 (CMD.EXE)
[edit]TIME [hh-mm-ss] [/N]
Note: /N means no prompt for TIME.
Windows (CMD.EXE)
[edit] 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
[edit]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.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
