This Sunday, 015959 US local time will be immediately followed by 010000, in all states/provinces that observe DST. This means that local apps will experience reverse clock-slew, and that multistate networks will experience multiple incidents of clocks-out-of-phase, *if they work off local time instead of UTC* (which all apps should do, internally, to avoid this). If you can't plan or test ahead, at least keep an eye on things, to avoid... outages. Have a nice weekend, all. :-) Cheers, -- jr '<moderator>' a -- Jay R.
