MySQL Timestamp values

Brad Selfridge
MySql supports a timestamp value of '0000-00-00 00:00:00' which is obviously an invalid DateAndTime and Timestamp. Do we need to create a MySqlTimestamp class that allows the creation of a "minTimestamp", which would contain a '0000-01-01 00:00:00' value (which is valid), but when printed returns a '0000-00-00 00:00:00' string value?

What would be the advantage of having a TimeStamp with no date?

What are you trying to achieve using a zero year? Christian chronology? :)

Regards!

One obvious usage is to record recurring times. e.g. I have a daily schedule, I want events, and I want them sorted by time, but I don't want dates on them.
