Fix bogus timetz_zone() results for DYNTZ abbreviations.
timetz_zone() delivered completely wrong answers if the zone was
specified by a dynamic TZ abbreviation, because it failed to account
for the difference between the POSIX conventions for field values in
struct pg_tm and the conventions used in PG-specific datetime code.
As a stopgap fix, just adjust the tm_year and tm_mon fields to match
PG conventions. This is fixed in a different way in HEAD (388e71af8)
but I don't want to back-patch the change of reference point.
