There are two instances of 0230 but only one 0230 EST and one 0230 EDT. So that could take care of the ambiguity, if the officer were clever. Or he could use UTC/GMT/Zulu, if the office had a military background. Or, how about this for a laugh... Suppose DST were implemented with +/- leap hours. Consider if the DST switch were made around midnight instead of 2 AM. Then the Spring DST change would jump from 22:59 to 00:00 skipping the 60 minutes labeled 23:00 to 23:59. The Fall DST would be implemented after 23:59 where and extra 60 minutes labeled 24:00 to 24:59 would be added. That takes care of your EST/EDT ambiguity... /tvb http://www.LeapHour.com
