Showing that EST with DST applied is not an appropriate Local time but in this example there are two timezones that are (there are in fact, 4 I believe). Of course the computer concerned may not have had DST applied at the time the record was applied (as suggested by the registry information supplied) or the user was in a different time zone or the software concerned didn't care about DST...
Going back to the original question I would say it would be foolhardy to make any assumptions about local time from this one artifact. Try and stand in a court and make a definitive statement without absolute and unequivocal knowledge is foolhardy at best and tantamount to suicidal at worst.
