ircII help: timer

Usage: TIMER [-refnum <num>] [-delete <num>] <seconds> [<command>]
  Waits for the given number of seconds and then executes the
  command.  This is done without hindering normal operation of
  the client.  Any number of TIMERs can be set at once, and
  all will activate at the appropriate time.
    TIMER with arguments will list pending TIMERs.
    TIMER -refnum <num>
  will assign a specific number to that action allowing you
  to delete it later if necessary with
    TIMER -delete <num>
  If no refnum is specified, one is automatically assigned.
