The generally accepted method (AFAIR) is yyyymmddxx,
where xx starts at 00 and is incremented for each change during that day. This
allows for multiple updates in a single day without causing problems for
situations such as 3 updates today followed by one update each day for the next
4 days ... Of course, if you never manually update the zone file, this isn't
really an issue ;)
