I used to set default_value => \'current_timestamp' but that didn't work for MySQL, which wanted \'NOW()'.
DBIx-Class-TimeStamp offers a truly cross-database solution for timestamping the creation or update of records.
@Moritz Onken: All tests pass for me with v0.12.
Very nice module. Easy to use, does what it says.
A lot of failing tests, though. Therefore only 4 of 5 stars.
