My N9 with PR 1.3 does not update time when I travel from New York to Chicago (I assume this should be the case if I were to travel from miami to LA as well).

In PR 1.1(and also 1.2 I think) I have seen the time update automatically during my travels. Not sure this is a defect in PR 1.3

Note:
I have enabled the "Automatic time update" on Settings->Time and language->Time and date screen.

Please let me know if anyone has encountered this same issue and point me to the solution.

Thanks in advance for all your help.
