GoDaddy Bobbles DST Changeover? 201
Several readers alerted us to this piece in PC World reporting on concerns that GoDaddy might not be ready for the DST changeover. Some readers, and others, claimed that GoDaddy's servers are not reachable now and are not serving email or web sites; but others see no evidence of this. The article recounts the rather flip response one GoDaddy customer got from their tech support: "As Daylight Savings [sic] does not apply to our servers, since we are on Arizona Time and our time zone does not change, our servers wouldn't update." When IDG News Service contacted GoDaddy they got an altogether more sensible reply.

Windows maintains its internal clock as UTC. Things just get too messy otherwise.
Windows does not currently have working support for a CMOS (hardware) clock that is not set to local time. It converts the internal UTC time to local time before updating the hardware clock, and when reading the hardware clock, Windows assumes it is set to local time. (This is rather silly if you ask me. Unfortunately, nobody ever asks me.)

GP is correct, actually. Suppose a user schedules an event for 9 am local time. The server re-maps this to UTC, then stores the UTC time. Then, government comes along and changes the mapping between local time and UTC by rescheduling the start of DST. Now, when the server maps back from UTC, the event ends up as 8 am local time. This is probably not what the user wanted.
you're an idiot.

Whether it's done in UTC or local time zones, having local decisions made based on the local time can be problematic when hardware, firmware, and software manufactures don't provide updates.
The DST has changed. I am now taking inventory of hardware that didn't properly make the change. I don't count things like the digital clock in my car, because it doesn't support DST in any way.
Items that have failed and support DST and still failed include my wall Atomic Clocks, and my Linksys Router with the latest (Feb 2007) firmware updated. The manufactures website on both of these items makes absolutely no mention of the DST change as if nothing happened.
I have work-arounds for both failures. It involves turning off the broken DST and changing the time zone one zone to the East. The Linksys router is a non-issue for most folks, but I use the clock for access restrictions, otherwise the school age kid requires lots of prodding to get offline and go to bed. Having his access shutdown eliminates lots of nagging.
Why can't Linksys even admit the issue and state on the website the latest firmware update did not address the issue? I should not have to check to see if the software is working properly. I think I will submit a bug report and see what happens.

Strange. My atomic clocked changed just fine. Also, I was always under the impression that the DST function wasn't built into the clock itself, but into the data stream coming from WWV or WWVH (depending on your location.) Maybe you live somewhere that your clock ended up locking into CHU, the atomic clock in Canada, or the one in South America (call letters escape me right now). I've picked both of those up loud and

I've never seen a clock that synced from CHU (3.33 MHz and 7.335 MHz)...or from WWV/WWVH (2.5, 5, 10, 15 and 20 MHz), for that matter.
The clocks and watches that feature "atomic time" use the signals from WWVB on 60 KHz.

Could be a Windows issue? Windows and PCs usually store local time, and map back to GMT through time zone info.
Where as most UNIX installs, and PC-UNIX installs where you choose network time on install would work the other way.
The important difference is GMT0 is network time, thus not calculating it once again has advantages. I have 3 un-patched systems running on the internet right now, all work just fine. Sure, a email header might be out an hour but it shouldn't make any difference.
Windows uses UTC internally (Score:2)
Windows expects the hardware clock to be set to local time (mainly because that's all MS-DOS could understand, and so Windows follows suit). Windows does store time internally in UTC. So upon startup, it reads the hardware clock, converts it to UTC, and runs with that.
