TIME

Displays the system time or sets your computer's internal clock.

Note: Every time when TIME command is called, MS-DOS waits for 
you to enter current time. You can just press ENTER to pass it. 
There is an additional feature in Windows NT/2000: To show the time 
without modifying it, apply "/T" switch to it.

For more information, please refer to MS-DOS Help or Windows NT 
command line command help.
