I believe postgres_fdw sets the timezone in its remote session to UTC
for predictability of results.  Your table definition is really at fault
for being dependent on what the session timezone is.

Personally I'd make the ins_ts column be timestamp with time zone, but
if you really don't want to do that, you could consider making the default
expression be "current_timestamp AT TIME ZONE 'something'" to force the
rotated value to be in a particular zone.
