I've never worked out which of these two is used, so I guess you have to edit both. For Victoria, NSW, ACT, and Tasmania: search for "AEDT" in the file, and change the TZ line to TZ=AEST-10AEDT,10,1,0,7200,4,1,0,7200,3600 (Then change the actual clock, because it's probably already done a premature switch of one unwanted hour.) This should also get the change correct next October, unless they go and change the legislation again. For South Australia: similar to above, but CST-9:30CDT instead of AEST-10AEDT. For Qld and NT: no change needed, I don't think they ever switched to summer time. For WA: I'm not sure. My copy of eClock says that Perth doesn't observe daylight saving time, but I have a strong suspicion that that's wrong. Google tells me that WA did in fact end summer time this weekend, unlike the eastern states, but eClock doesn't seem to know about that. (If anyone is still puzzled about WA, let me know and I'll take the effort to work out the correct TZ string, because I do have it documented somewhere.) The one thing I haven't managed to find out is how to find a time server I can synchronise to. All the old favourites seem to have stopped working. -- Peter Moylan peter at pmoylan dot org http://www.pmoylan dot org -------------------------------------------------- http://www./melbpc/ - The Melbourne OS/2 SIG === **= Email 2 ==========================** Date: Sun, 29 Mar 2009 18:41:33 +1000 (EST) From: "Peter L Allen" Subject: Re: Daylight saving time-a.nist.gov 129.6.15.28 Worked for me just now, allenpl On Sun, 29 Mar 2009 16:27:14 +1000, Peter Moylan wrote: >In answer to the question everyone asks twice a year: the eCSClock files >you have to alter are in the directory C:\ecs\system\eclock and the >files you have to alter are called tzdata and tzdata.international.

For the first time in many months I have a synchronised clock. It still surprises me that the Australian time servers aren't available. Ah, but now that I think of it they were mostly university servers. Their disappearance seems to have coincided with the rise of the philosophy that universities are for-profit corporations, and therefore shouldn't provide anything free to the public. -- Peter Moylan peter at pmoylan dot org http://www.pmoylan dot org -------------------------------------------------- http://www./melbpc/ - The Melbourne OS/2 SIG === **= Email 4 ==========================** Date: Sun, 29 Mar 2009 20:30:46 +0930 From: "Paul Smedley" Subject: Re: Daylight saving Hi Peter ------- Original message ------- From: Peter Moylan To: os2genau at os2 dot org dot au Sent: 29.3.'09, 14:59 > In answer to the question everyone asks twice a year: the eCSClock files > you have to alter are in the directory C:\ecs\system\eclock and the > files you have to alter are called tzdata and tzdata.international.

Thanks for this - perhaps we should open a ticket at ecomstation dot com to get the TZ stuff correct for eCS 2.0 > For WA: I'm not sure.

WA is currently taking part in a 3 year trial of daylight savings - with 1 more year to go until the trial ends. cheers, Paul. -------------------------------------------------- http://www./melbpc/ - The Melbourne OS/2 SIG === **= Email 5 ==========================** Date: Sun, 29 Mar 2009 21:19:27 +1100 (EDT) From: "Ian Manners" Subject: Re: Daylight saving Hi both Peter's, >> time-a.nist.gov 129.6.15.28 You can also use 128.250.33.242 which is Melbourne Uni (mumnunah.csse.unimelb.edu.au) Possibly also 210.10.87.158 and 192.189.54.17 but likely only if you have an Australian IP (they could have changed that).

However, a note of caution: 4 character timezone names cause problems for anything based on the EMX runtime, which only supports 3 character timezone names :-| If it encounters a 4 character name, it does everything in GMT...

Which is why I use :- SET TZ=AET-10EDT,10,1,0,7200,4,1,0,7200,3600 Not sure where I got AET from, think it was from Uni/institutes zone abbr file. AET = Australian Eastern Time. The rest I worked out manually, probably like Peter Moylan did. And Paul is correct about WA, silly thing is daylight saving in WA is much worst than in the East as during summer the sun is higher in the sky compared to the eatern states, so adding the hour makes it still daylight after 9pm. The Eastern states need daylight saving a lot more than the west does. Ever tried to get kids to bed while the suns still up ?
