Dave,
Check your date and time settings - Settings<>General<>Date & Time... then make sure your time zone is set to your actual location and time zone. Tell us what you find after checking this stuff out.
No - the iPad doesn't use NTP servers. I'm not sure why. Download the free app, 'Time', and you'll see what the NTP servers are saying. There's also a very informative Information page in that app which describes how the iPad receives time updates (via 3G) but not via WiFi.

You made me think then lol but the time on the pc is correct but all my location stuff is set for uk on the pc maybe the iPad thinks the pc is in the uk and because the iPad is set to Paris the sync adds a hour
It's not 3G yes I can set it myself but its not really the point it should keep time after I set it i would like to use the alarm but it's not reliable
