<title>Incrementing and Changing the Serial Number</title>
- <para>
- Zone serial numbers are just numbers — they aren't date
- related. A lot of people set them to a number that represents a
- date, usually of the form YYYYMMDDRR. A number of people
- tested these numbers for Y2K compliance and set the number
- to the year 2000 to see if it would work. They then tried to restore
- the old serial number. This caused problems because serial
- numbers are used to indicate that a zone has been updated. If the
- serial number on the slave server is lower than the serial number
- on the master, the slave server will attempt to update its copy of
- the zone.
