Sounds like you may be hitting the menu button instead of the OK button when you are setting the Date/Time. If you hit menu it does not save the new settings. Are the new date and time shown in the exif data for pictures taken prior to turning the camera off? Ken.
Thanks for the reply Ken.
No, I am using the "Enter" button and following the procedure correctly. Its the same as my Fuji S5000 so something I am familiar with, as on that camera the date has to be reset after removing the batteries for recharging. If I set the date correctly, and then take a picture without turning the camera off, the correct date and time is stored in the exif data. If I then power the camera off and on again, the date goes back to 1-1-2006 and time to 00-00. This wrong time and date will then be shown in the exif data of the next picture taken. Weird eh? Another problem I noticed is that if I plug the camera into my PC and download photos to Googles Picassa programme, some photos are in the wrong order they were taken. I guess thats because the time and dates are all wrong. If however, I put the SD card in to my PC's card reader slot, they then down load correctly!
I think a visit to the repair shop is in order, but thanks for your suggestion.
