A timestamp is a timestamp. It isn't a date. If you need a date, use a proper date/time data type.

All timestamps have to start somewhere. If you want to avoid DST changes and leap seconds, you can use MJD, TAI or GPS time instead of UTC, but you might as well format it nicely so that you can see roughly at what (civil) date something happened.
