Display the current date and time or set a new date and time.
date [options] [+format]
date [-su] [MMDDHHMM[[CC]YY][.SS]]
-u displays or sets the time using Greenwich Mean Time (GMT).
The date command alone displays the current date and time. Using the +format argument, you can specify a display format for the date and time. For a complete listing of the format specification, type man date.
To set the date, use date followed by the date and time in the MMDDHHMM format, where each character is a digit (MM is the month, DD is the day, HH the hour, and MM the minutes). You can optionally specify the year (YY) and century (CC) as well.
