That's rubbish! Dates for advancing and retarding the clock are fixed for
any given country. If they weren't then there would be potential accounting
nightmares each time the country's clocks changed. The majority of
countries in the northern hemisphere change their clocks on the last Sundays
in March and October although DST commences on the first Sunday in April in
North America (except for Hawaii and Arizona which don't observe DST -
although the Navajo parts of Arizona do). There are other exceptions but it
only requires a small lookup table. Windows never asks me to confirm
daylight saving time changes and these are also handled correctly (at least
for me in the UK) by my Garmin etrex and Vista receivers.
