NAME
date - print and set the date
SYNOPSIS
date [ mmddhhmm[yy] ] | +format ]
DESCRIPTION
If no argument is given, or if the argument begins with +,
the current date and time are printed. Otherwise, the
current date is set. The first mm is the month number; dd
is the day number in the month; hh is the hour number (24
hour system); the second mm is the minute number; yy is the
last 2 digits of the year number and is optional. For
example:
date 10080045
sets the date to Oct 8, 12:45 AM. The current year is the
default if no year is mentioned. The system operates in
GMT. date takes care of the conversion to and from local
standard and daylight time. Only the superuser may change
the date.
If the argument begins with +, the output of date is under
the control of the user. All output fields are of fixed
size (zero padded if necessary). Each field descriptor is
preceded by % and will be replaced in the output by its
corresponding value. A single % is encoded by %%. All
other characters are copied to the output without change.
The string is always terminated with a new-line character.

n insert a new-line character
