Hi M.Vinitha devi,
Thanks for checking, now it also works fine here. But yesterday, it didn't work for all our clients, all browsers and all os systems. So it is a bug when the Daylight Saving Time is not rollout yet for all the timezones. You checked it more then 24 hours later than the clock change of sunday night.
I hope you can fix this for the next clock change, otherwise we have then the same problem.
