Unfortunately, this is not entirely true. Certain operating systems track
local time, rather than UTC, and thus will report incorrect UTC times to
applications if the timezone is not correct. Further, users are prone to
deciding that the time they see is wrong and "fixing" it by changing the
time rather than selecting the correct timezone. It seems not unlikely
that a good portion of users will do so in response to the upcoming
brokenness ("Oh, I know the rules changed; my computer must have done it
wrong, so I'll just set the clock now").
Of course, systems using NTP with a reliable time source should have no
problems, as long as the user does not tamper with the clock.
