You'd need to use a timer set at the right time and basically do this (any of the following):
/timerHourTime 0 3600 /echo -s $!asctime($ctime)
/timerHourTime 0 3600 /echo -s $!timestamp
/timerHourTime 0 3600 /echo -s $!time
etc etc etc. In case you didnt know, Im using the ! so it evaluates when the timer fires as opposed to when you set the timer. Does that help?
