     USAGE
     
     Until is  used to  wait until a given time of the day. It
     support two  time formats.  The first  list the  absolute
     time  in  hh:mm:ss  -format,  where  hh=hour,  mm=minute,
     ss=second. The time is parsed from left to right. That is
     a two  part time  represents hh:mm  and a  one part  time
     represents hours only.
     
     The second  format is given relative to the current time.
     This format is identical to the first format, except that
     it starts with a plus (+).
     
     Until can  be used for example in command scripts to wait
     to a specified time. It is equivalent to the
     at time  null-command, where null is a command which does
     nothing.
