21.1 date: Print or set system date and time

Synopses:

date [option]... [+format] date [-u|--utc|--universal] [ MMDDhhmm[[CC]YY][.ss] ]

Invoking date with no format argument is equivalent to invoking `date '+%a %b %e %H:%M:%S %Z %Y''.

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.

21.1.1 Time directives		%[HIklMprsSTXzZ]
21.1.2 Date directives		%[aAbBcdDhjmUwWxyY]
21.1.3 Literal directives		%[%nt]
21.1.4 Padding		Pad with zeroes, spaces (%_), or nothing (%-).
21.1.5 Setting the time		Changing the system clock.
21.1.6 Options for date		Instead of the current time.
21.1.7 Examples of date		Examples.
