We have an application that contains time based processing.
When clocks are moved back in the Autumn (Fall) there is obviously the possibility of overlapping times (something done an hour earlier would have the same time a something done now).
Setting servers to use UTC time, and adjusting the time display at the client end is an obvious solution, but would mean a fair amount of re-coding. There would then also the task of updating the existing data to reflect UTC time, rather than the local time.
The solution in the previous version of the system was to switch everything off for an hour.
Has anybody come across a more elegant solution to this problem?
