The "default text 'now'" hack doesn't work with TIMESTAMP columns, only
with DATETIME columns --- this was reported last month. I forget the
details but I think it is triggered by the presence of slightly
different sets of datatype conversion routines for the two types in the
system tables, leading to a different path being taken that evaluates
the default clause's value when it should not. Probably a default of
"now()" would fail for the same reason. Fixing this is on the TODO
list, but I do not think it is a trivial fix.
In the meantime, I suggest using a DATETIME column --- or two of them,
if you need the ability to record two different dates/times.
