Use fixed rate instead of fixed delay for the gc schedule

Erroneously, the gc was scheduled using a fixed delay. This caused the
start times of garbage collection to drift over time.

Now a fixed rate is used instead so that the garbage collection can be
scheduled to reoccur at the same time every day.
