I have a Garmin ETrex that I take on my walks. I don't use it much (as my cameras also has a GPS and generates a track log), so I only use the Garmin if I'm uncertain of the way (as the camera does not give OS grid references), but I keep the batteries charged should that happen.
Today when walking a stretch of the Offa's Dyke Path I needed to use it, as the mist descended. Whilst it was giving the correct co-ordinates as far as I could tell I noticed that it thought the sunset was after 9pm. That seems unlikely given it's February and looking more closely it seems to think that today is the 3rd July 1999 and is showing the time in BST (one hour ahead of actual).
I wondered if there was something been done with the GPS signals in the area, but I'm not home and it is still misbehaving and reporting an incorrect date and time.
Given that my understanding is GPS works off a very accurate time signal I can't work out how it has got the time so wrong - and there does not appear to be a way to set it manually.
Is anyone else having problems with their GPS, or is it just mine that has gone weird?
