Is your camera smart enough to automatically adjust for the move from Daylight Saving Time to Standard Time? It is worth checking.
Look into the menu system and find the time setting entries. There should be a mention of Daylight Saving Time. If so, check whether a simple On/Off setting is used; if so you’ll probably have to switch its setting on Sunday so that the time stamp on your photographs is correct (although you should check your camera’s user manual just to be sure).
