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.
