when i was in florida last year i purchased a watch from wallmart.today at work i suddenly panicked when my watch was showing 3.25pm...i realised i only had a short time left to finish the job at work..when i told my collegues how little time we had left ..they looked surprised and told me that it was only 2.25pm I am from uk so am i right when my watch has three letters also appeared on it "D S T"that this means daylight saving time in usa???is this the right time for my watch to correct itself??or has it done it prematurely as in uk we do not alter our time yet.....any help from across the pond appreciated....
