Wesley Bland 84be81df95 Standardize the initialization of the EPOCH's.
Everyone will be starting at MIN anyway (until we implement restart of course)
so there's no reason to set the epoch to INVALID and then immediately reset them
to MIN. This way there's less room to make mistakes later.

This commit was SVN r24829.
