Some time sync related automated tests fail when run on a system whose system clock is not in UTC
features/time_syncing.feature:{33,41,63,83}
and features/tor_bridges.feature:20
fail.
@boyska reports that running the test suite with sudo TZ=UTC ./run_test_suite
works around this bug.
This is a regression between 5.2 and 5.3.
I suspect 16f37753 is the culprit.
