Warn if timestamp updated_at field uses incompatible timestamp

resolves #10234

Problem

Snapshot tables use the 'get_snapshot_time' macro, which may be incompatible with the data type of the field specified as the 'updated_at' field, causing unexpected results.

Solution

Warn if the two sources of timestamp columns have different data types.
