Time Zone and Date
Explanation: Here you can set the camera clock and choose a time zone and the format to display dates.
Switching daylight saving time on or off will move the clock backward or forward by one hour immediately. It is no automatic change that will cause the clock to jump by one hour on the right day of the year.
Tips: Set time and date accurately.
A correct date is needed anyway to lookup when you have made your shots but I find also correct time important.
If you bring together pictures from different cameras it saves a lot of work if the clocks are set consistently in both cameras and you can simply sort all pictures by date & time the image was taken.
