Didn't We Do This Already? IT Folks Worried About New Daylight Savings Time Screwing Up Appointments

from the sounds-familiar dept

Back in 2005, there were some worries going around that after Congress changed the dates for Daylight Savings switches, that computers wouldn't be able to handle it properly, creating a "mini-Y2K" effect (as if there ever were an actual Y2K effect). Of course, it was a total non-story because most computers can handle that sort of thing, and the few that can't can easily be corrected without too much trouble. However, as we get a step closer to this year's Daylight Savings time shift, it appears that the worries are back, with consultants getting the press to talk about the potential for (once again) a "mini-Y2K" while mentioning (of course) that their consulting firms can help. Even IT people are getting into the act, sending out emails warning about potential problems not just with scheduling meetings, but flights and even concerts (say what?). Overall, this problem is a non-starter, but don't be surprised to see more stories warning you, while pointing you at vocal consultants willing to help you solve this "problem."

    Use UTC & zoneinfo

    It seems to me much of the time-related problems on Windows systems arise from two causes:

    1. The fact that their system clocks are set to local time, not UTC, and
    2. Their use of a proprietary format for timezone and daylight-saving info, instead of the industry-standard zoneinfo format.

    UNIX/Linux systems have kept system time in UTC for decades. One consequence of this is that they always know what time it is. And use of zoneinfo means they can always get updates from the source, without having to wait for vendor updates or resorting to low-level patching.
