Process start time not showing correct time

Process start time is not showing the correct time:

I had started a process on Jun 17th at 23:30:00.
Next day morning when I run the command "ps -ef | grep mq", the process is showing the start date of Jun 17th but the start time is 00:16:41

Day/Date is setup correctly on the server.

It is not that the process took that long time to startup as the process was available right after the it was started at 23:30:00

Any suggestions?

And absolutely nobody else could have stopped & restarted the process. Somebody with either su or root.

Absolutely sure that no one restarted the process. The weird thing is that the Date is correct "Jun 17", just the time is incorrect.

According to the time 00:16:41, it should have displayed "Jun 18".
