I don't think the RTC battery being dead would affect sleep times. 5
hours in 1970 (or whenever) are the the same length as 5 hours now.
If you want to anything more complex than can be achieved with cron,
it's probably better to install one of the cron replacement ports,
such as fcron. I don't see any reason why one of these couldn't run
in parallel with the existing cron, or you can turn-off cron in rc.conf.
