trip counter clock on 05 Fazer 100

[bedrock]

Hi guys wondering if anyone has had a problem with the trip counter on their bikes going to zero once the ignition has been turned off when the ignition is switched back on the clock always reads 1.00 am,
When I switch the ignition back on reset the clock to the correct time and start riding again trip and clock work fine until I turn the ignition off again.
I would appreciate any advice as I am no good with electrics.
Cheers
Colin
