Automatically resetting leaderboards

In John Carmack's app review of Space Shooter he says:

For anything vaguely arcade game like, having shared scoreboards will add value. Having daily and weekly resets, as well as the all-time-high (since last behavior changing update) list will allow more people to experience being on them.

Is there a way to set a leaderboard to automatically reset on a daily or weekly basis?

Thanks,
