`date': Print or set system date and time
=========================================
`date' with no arguments prints the current time and date, in the
format of the `%c' directive (described below). Synopses:
date [OPTION]... [+FORMAT]
date [-u|--utc|--universal] [ MMDDhhmm[[CC]YY][.ss] ]
If given an argument that starts with a `+', `date' prints the
current time and date (or the time and date specified by the `--date'
option, see below) in the format defined by that argument, which is the
same as in the `strftime' function. Except for directives, which start
with `%', characters in the format string are printed unchanged. The
directives are described below.
