I guess we got jumbled in time calculation.
I had scheduled time for 11.30pm-12.00 am India time IST
And I informed at 9.30pm India time.
Thus we can play at 11.30pm or 12.00 am IST time... i guess DST time mismatch happened.
Sorry guys, since we in India don't have DST time etc calculation I made the mistake.
(i.e. our time remains same throughout year)
