It sounds a bit bogus to me too. Another possibility is to keep the
data storage as timestamptz (which is really the recommended type for
any sort of real time values), and define the index on
date_part('day', entry_time AT TIME ZONE 'GMT')
(or whatever zone you choose to use for reference). However, to use the
index you'd have to spell the queries exactly like that, so the PITA
factor might be too high.
