I took Richs question to mean can you change the time portion supplied
by Postgres, so:
Instead of '2013-01-21' having the time portion set to local midnight it
could be set to a user supplied value say, 08:00:00. That is not
possible, correct. In the absence of a time portion a date string
supplied to timestamp will always get local midnight?
