It takes around four hours for a freshly charged main battery to charge the internal backup battery. It you do that and it still doesn't charge it, you need a new internal battery. The fully charged internal battery in most of them will hold the charge for up to 3 weeks with the main battery out of the camera.

Check the timezone if it is right. Timezone must base were you live. For example, if I live in Hongkong, this is my correct timezone - (UTC+08:00) Beijing, Chongqing, Hong Kong, Urumqi. Check also if the the settings of your date and time is set to windows. If it set to windows then the timezone is set to US then you live in Hongkong your date and time will always adjust to the time of US even if you always adjust your date and time to Hongkong. I hope my explanation is clear to you. =)

If it's been a few months since you have used the camera it's normal to be dead.
Charge the camera and use it and the clock battery should come to life.

The camera will work fine even if the battery does not work, however, you will not be able to record time and date.

Most of the cameras with a date time clock have a secondary internal power source like a small watch type battery some point and shoot cameras use a storage cell which takes power from the main battery. This means when the main battery looses power the camera clock will hold a setting for about 1 day or 24 hours. To keep the camera clock set you need to keep a charge in the main battery. Here is a screen shot from the manual explaining this function.

No internal battery. After the batteries are in the camera for 2 hours, there is enough charge in the camera to hold on to settings for 6 hours. If you take longer than that to install fresh batteries, the settings are lost. Here's what the manual says:

DATE/TIME

DATE/TIME

OKOK:At the time of purchase and after leaving the camera for a

long period with the batteries removed, settings such as the

date and time are cleared. Once the AC power adapter has

been connected or the batteries have been installed for 2

hours or more, the camera settings will be retained for

roughly 6 hours even if both sources of power are removed.
