I have tried reproducing the issue at my end with the demo and in the application but no avail.
Referring to this forum
thread: It was due to Daylight Saving Time. There was a lot of written in the
forums, you could search to find the discussions from last year.
In short when you select 30 March 2012 00:00:00. It turns back to 29
March 2012 23:00:00. Which is the previous day. And this happens because
due to the DST the 30 March 2012 00.00.00 actually does not exist as
time. In given region two seconds after 29 March 2012 22:59:59 the time
is 30 March 2012 00:00:01.
