On Jan 1, 2008 Venezuela changed its timezone from UTC-0400 to UTC-0430.
Fedora was on the ball and adjusted pretty quickly, likewise Windows,
however Firefox had an interesting Javascript bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=411726 initially reported
on MacOS X but later confirmed on Fedora 8. It took about a year to fix.

IOW, even though the platform gets it right, some apps may still get it
wrong because of hidden assumptions, e.g. that timezones are always
integral numbers of hours away from UTC.
