My clock is about 5 mins fast.
If I set it to the right time, then 24 hours later it is 5 mins fast again, but after that it doesn't seem to get more than 5 mins fast.
I've just tried fooling it by setting it 5 mins slow (about 4 hours ago), just to see what happens, but I won't know the result of that for a while yet. At the moment it is 4 mins slow.
Oh, and it only does this when DST is in effect, up until a week ago it was keeping perfect time. Just in case someone asks, Internet time synchronisation is OFF.
Anyone ever seen anything like this? It is driving me nuts.
