LP#1485374: call tzset() after setting timezone

Testing shows this to be needed to make strftime()
return the time in the client's time zone.

This is a bit confusing, however, as strftime per
POSIX should be acting as if it always calls tzset()
when doing formatting that involves the local timezone.
