I notice today that as the clocks have been put forward 1 hour something seems to have gone through my whole file system and added 1 hour to the timestamp on every file. Is this a MS brainchild? It means that all my backup folders now show as being different from the ones on my main machine. 100s of gigabytes of data to resynch. If it is a MS idea is there some way that I can stop this happening in future?
