[Bug 1353069] Re: db_format_tsfield() returning time value with offset on POstgres

 

Attaching an improved version of the timezone troubleshooting patch.

It turns out my problem was that my Postgres database was using the
timezone "GMT" for some reason, instead of "Pacific/Auckland".

Bug description:
  On postgres db_format_tsfield() calculates time by doing
  FLOOR(EXTRACT(EPOCH FROM {$field})) which apparently doesn't make
  sense if we are using fields without timezone (by reading this
  http://postgresql.1045698.n5.nabble.com/Possible-problem-with-EXTRACT-
  EPOCH-FROM-TIMESTAMP-td2125933.html).
