Hello, I need to account for daylight savings time in list of data representing each hour in year 2010. I would like to correlate that with other data taken at 15 second intervals in the same year. In 2010 daylight savings time in the US began on 14 March 2AM. DateDifference[{2010, 1, 1, 1}, {2010, 3, 14, 1}, "Hour"] (*1728 hours after beginning of year*) DateString /@ (DatePlus[{2010, 1, 1, 1}, {#, "Hour"}] & /@Range[1728, 1738]) (*doesn't reflect that 3AM should follow 1AM*) In hindsight, this is not surprising because daylight savings time shifts are not standardized intranationally or internationally. I don't see any clever work-around. Does anyone else? Craig W Craig Carter Professor of Materials Science, MIT
