Depending on the way you mostly use your columns, you can also do the
opposite: store date/timestamp into "pieces" in different columns
(century, month, day, hours, minutes, seconds, milliseconds, time zone
shift) and reconstitute a whole date/ts into an auto-generated column.

Sometimes, you have to break the rules, especially with a large number of
rows, because pre-calculation is way better than post in this case.

Depending on your needs, you might also be interested into that:

BTW, don't leave us dry, share your progress and results *<;-)
