A trigger isn't going to help in the least for that; the data has to be
a valid timestamp before the trigger will ever see it.

The usual trick for this type of conversion is to load the data into a
temporary table that has simple column types (eg integer or text) and
then do your transformations during an INSERT/SELECT into the real
target table.
