I believe that the Aussie Time zones are usually abbreviated "CAST", "EAST" and "WAST" to prevent this confusion. (for ___ Australian Standard Time, the ___ being Central, Eastern, and Western...)

Maybe overseas, but not here.
The abreviations only change from WST, CST & EST when daylight saving confusion kicks in.

Well, it doesn't make things better, that CST also stands for "China standard time" = UTC+8, and for "Cuba Standard Time" = UTC-5...

So, CST = -6 -5 +8 +9.5 = ...

Hmm, should it be summed, or averaged, or...

EST isn't better, since EST = -5 -3 +2 +10

Only WST has really any meaning, since WST = +8

Or for that matter, PST = -8 +5 +8


It's much better to use UTC +- than using any of these abbrevations that clearly isn't unique.

Unfortunately most people wouldn't know what UTC is (although they may have heard of GMT), let alone how many hours forward or back it is from their time zone.

That's another whole ball of wax. Trying to keep up with daylight savings time. Some people don't observe it. Also, when we here in the States are changing one way Australia is changing the other way. Spring here is fall there. UTC doesn't change but it helps to know which way someone is going when you try to tell them what time it is.

Yup and this one has been tossed around since the dawn of time ..... pun intended ..... and each tine it has, we always get back to a constant reference point, GMT/UTC (still mystifies me why some clown started up "UTC" its the same damn thing as "GMT" - talk about reinventing the ego wheel}.

Sure does, and as more people get involved, and more discuss it yet again, we will have more understanding that the easiest way round the whole nightmare is a peg in the ground and refer everything to that peg (GMT/UTC) - then at least we only have two times (at least most do) to cope with, the summer and winter version which is only an hour apart.

Its not rocket science, and most get it when meeting up with it - the rest? Well I guess they will still go through life being an hour early or an hour late for work twice a year - aint that life :)

They did it for the same reasons Historians quit using B.C./A.D. and went to BCE/CE when referring to dates: It's the Politically Correct thing to do.

It's just so plain stupid...

But GMT isn't UTC. Well maybe if you don't care about anything less than a couple of seconds difference. There are people who do.

GMT is based on how fast the earth turns. That isn't a stable rate.

UTC is based on how fast caesium vibrates. That is a stable rate.

Every so often UTC has to be adjusted to keep within a second of GMT. That is when you hear about a leap second.

For 99.999% of people, a couple seconds difference between UTC and GMT has zero meaning and zero influence, and most doesn't even know there are a difference. Many doesn't even know there's anything called UTC.

If you're looking at the 100-meter sprint or something, a couple seconds is a huge difference, and everyone would see the difference.

The difference between the clocks being 06:57:46 or 06:57:47 on the other hand is for most irrelevant, the bus or train or whatever doesn't go exactly on the second anyway... Would guess, most peoples watches shows more than 1 seconds error from the "correct" time anyway...

The max difference allowed between UTC and GMT is 0.9 sec. And usually is corrected long before that.

My guess - aside from the earth rotation/ceasium vibration bit - is that they came up with UTC to get away from the "Greenwich" that is in the GMT acronym.

The "UTC" acronyom is from French words, BTW. In English, the acronym should be "CUT" for "Coordinated Universal Time".

If I remember my history the French wanted the Meridian to run through Paris
but as the British were more convincing/forceful(courtesy of Harrison's chronometer) we won that round,They never forgave us and Universal Co-ordinated Time sounds just as good to me.

Not quite. In English it would be CUT, and in French it would be TUC. They couldn't decide which to use, so as a compromise they picked a third alternative that is grammatically wrong in both languages :)

Actually, according to Wikipedia, here, UTC is a compromise backronym as the time body wanted an "universal" acronym that would fit all languages.

Fixed your link (had to take off the trailing "/").

In any case, it's human controlled and therefore prone to error.


Hmm... nothing a little awk, sed, and cron couldn't fix.
