STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set system time zone to Irkutsk (GMT +8) with/without DST also set it UlaanBataar timezone


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
  Program output should match with actual system time
ACTUAL -
  Program output does not match with actual system time

REPRODUCIBILITY :
This bug can be reproduced always.
