In US, the Daylight Saving Time stopped today. Many modern gadgets can adjust the time automatically but many cannot. The same applies to digital cameras. It is probably a good idea to check your camera for the accuracy anyway. Some camera can sync time with computer when connected via a USB cable. However this may not work if you have been transferring photos using card readers all the time.
If your camera is made before 2007, it might have ended the Daylight Saving Time one month earlier because Daylight Saving Time in US was extended one month beginning in 2007.
