Is this standard behavior?

Based on your description, it sounds like the master was out of touch for 10
days and the zone expired. Given that no zone transfers occurred during that
10-day period, and therefore the slave copy of the zone was not
overwritten/rewritten, it makes sense that the timestamp did not change during
that time.
