It really helps if you use precise language when discussing problems.
date, time with time zone, time without time zone, timestamp with time zone,
and timestamp without time zone are all different types.

That can not give you a result that is an interval if datevar and datevar2
are actually dates. They must be some other type, probably a timestamp
of some sort.

If the date variables are of type timestamp with time zone you should
be OK. You probably want to test comparing dates in different time zones
(if you have different time offsets from GMT at different times of the year
at your locale, e.g. daylight savings vs standard time) to make sure you get
the expected result.
