This looks very odd.  It's possible that you create multiple interval
timers (before you find that REALTIME >= 0), but you only store the ID of
the last one, so all but that one can't be cancelled.

It appears that you want to keep checking some time to take action later
in the else clause.  Can't you calculate when REALTIME will become >= 0?
Then you could use setTimeout.

Please learn to use local variables.
