It should do it within an hour.

No.

The name server maintains a log of the dynamic updates
it's processed, by default called <zone data file>.log.
If the name server rewrites the zone data file, it deletes
the log file.  If the name server crashes, it'll find the log
file next time it starts and will update the zone accordingly.
