I have now got the RTC working fine, thanks for the pointers.

One last question to anyone who reads this I'm setting the clock from a GPS which provides GMT.
I want to configure the GPS to configure the RTC for different time zones which I should be able to do from the Lat & Lon from the GPS. But before I go and write a routine has anybody done this before?
The biggest problem will be adding say 1hour when the clock is at 23hr as I then have to increment the days and possibly the months and possibly the years.
