Right, which is why Tom had in his example:
regression=# set datestyle = dmy;
BTW, my recommendation would be to store in a timestamptz field *with
the correct timezone*, and then convert on output as necessary. This is
easy to do by either
SET timezone
or
SELECT timestamptz_field AT TIME ZONE '...';
If you want the time without DST, you can just use a timezone like '+8'
or '-8'.
Since you're dealing with GPS data and presumably have lat/long, it
shouldn't be hard to do this dynamically either, either by just blindly
dividing longitude by 15 or using actual timezone shape polygons and @>
or <@.
