The date and time will not stay set. I set the date time . take pictures and when I shut the camera off. the next time I turn it on the date and time is zeros again...

Usually when doing this you have to press 'Done' or something, not just go back to the menu. If you don't the date doesn't stick.

Replace the date battery as described on page 191 of the manual.

Taken from manual:

There is a button battery in your camera (CR1220) that remembers the date and other settings when you remove the main batteries. It probably needs to be replaced. It's in a slide-out holder next to the AA batteries (see page 184 in the manual).

You turn on the date stamp by using the photo size settings. Press the Function key and scroll down to the bottom item (usually L). Then scroll over to the Date Stamp icon (to the right of the L, M1, M2, M3, S options). Press the Function/Set key again.

The date stamp only works in "Postcard" resolution. Press the "Func Set" button, then scroll down to the bottom to select postcard resolution.

Then press the menu button. Select the "Camera" menu, then scroll down to the the Date Time Stamp selection to turn it on.

to keep the date on, you have to leave the camera off with a charged battery for 24 hous to charge the inner battery that keeps date on. If this doesn´t solve the problem then is because the inner battery won´t charge anymore, but it will take pictures as normal without the date. To avoid this don´t leave the camera too long without use or with a worn battery.

First you have to go to the set up menu and set the correct time and date, then you can go back to the settings and select OFF for time and date. If you do not set the correct time and date , that default date stays in the picture.

I suggest u to contact the service people and they will change the internal battery to keep update with time and date. Every camera has internal small battery so has to change regularly
