Name
       date - print date and time

Syntax
       date [-c | -u] [ +format ] [[yy[mm[dd]]]hhmm[.ss][-[-]tttt][z]]

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 clock); the second mm is the minute number;
       .ss  the second; -[-]tttt is the minutes west of Greenwich; a positive number means your time zone is west of Greenwich (for example, North
       and South America) and a negative number means it is east of Greenwich (for example Europe); z is a one letter code indicating the dst cor-
       rection mode (n=none, u=usa, a=australian, w=western europe, m=middle europe, e=eastern europe); yy is the last 2 digits of the year number
       and is optional.  The following example sets the date to Oct 8, 12:45 AM:
       date 10080045
       The current year is the default if no year is mentioned.  The system operates in GMT.  The takes care of the conversion to and  from  local
       standard and daylight time.

       If  the	argument begins with +, the output of is under the control of the user.  The format for the output is similar to that of the first
       argument to All output fields are of fixed size (zero padded if necessary).  Each field descriptor is preceded by % and is 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.

Options
       -c     Perform operations using Coordinated Universal Time (UCT) instead of the default local time. The UCT does not use  leap  seconds	so
	      UCT is the same as GMT.

       -u     Perform operations using Greenwich Mean Time (GMT) instead of the default local time.
