Title: Daylight Saving Time Issues In 2007
Post by: dougeeebear on October 28, 2006, 02:52:16 pm
Starting in 2007, daylight saving time will start in March and end in November (as opposed to April and October).

I have also heard that this is a test to help reduce energy cunsumption and will be studied and is subject to change again in 2008.

That means if we set the zaurus clocks ahead in March, the zaurus will also automatically set them ahead again in April.
The same would be true in October/November (only in reverse).

There has to be some kind of a work-around found for this.
Maybe it would be to just patch the system to not change the clock, or maybe a program that would allow you to specify the dates for switching.

Does anyone have any ideas about how to go about something like this?

The only thing I can think of offhand is to change my time zone to one that doesn't observe daylight saving time (such as Phoenix, Arizona).
But I wouldn't really want to do that, only as a last resort.

Wouldn't it just be a matter of updating the timezone ipks and pointing the right one to your /etc/localtime

What I want to know is why we use it up here.  Our day/night cycles change so much what's the point?

Has anyone come up with a work around for daylight savings time? (Especially considering the change over in the US is this Sunday.)

Thanks.

You could try:

timezones_2007_all.ipk
http://www.tyrannozaurus.com/feed/beta3/cu...es_2007_all.ipk (http://www.tyrannozaurus.com/feed/beta3/custom/timezones_2007_all.ipk)

or

timezones_1.0.0_armv5tel.ipk
http://www.tyrannozaurus.com/feed/beta3/fe....0_armv5tel.ipk (http://www.tyrannozaurus.com/feed/beta3/feed/timezones_1.0.0_armv5tel.ipk)

Before you install one of these on the Sharp ROM, you have to remount the root file system as read/write.  For example, if the timezones_2007_all.ipk were on a CF card:

Code: [Select]
su
mount -o rw,remount /
ipkg install /mnt/cf/timezones_2007_all.ipk
mount -o ro,remount /
exit

other choice is to set timezone to GMT-7 or whatever, and manually change it whenever GWB changes his mind.

I suspect it's a big plot to smoke out all the windows pirates who can't download patches, and make them buy a copy of vista!!!

hmm - I have installed that package, but it gives problems when restoring a TAR backup of the timezone data.
I have backed up the entire root fs using tar / gzip after installing the new timezone package, and when restoring I get a lot of error messages from tar, such as

tar: usr/share/zoneinfo/Europe/Prague: Cannot create hard link to '/usr/share/zoneinfo/Europe/Bratislava': No suchfile or directory

What could be the reason?
Maybe the target file for the hard link is restored later than the link?
When I look into the directory after the restore, Bratislava is there, but not Prague.
Any idea how to assure a safe backup of all timezone links?

Thanks a lot
Daniel

I installed timezones_2007.ipk on my c760 and had to make a link to /etc/localtime and reboot to make the daylight savings change occur:

If your TZ environment variable is set, you might be able to type:

Code: [Select]
su
ln -sf  /usr/share/zoneinfo/$TZ  /etc/localtime

You could try installing timezones_2007.ipk again and then create the /etc/localtime link.

I misunderstood your question.  You could simply copy the time zone files that are linked rather than have hard links to the files.  These time zone files do not take a lot of space.  There should be no problem with the order of restoration then.

I installed the first IPK on my 860 running CACkO 1.23, and City Time and the calendar changed immediately at 2:00 > 3:00 ... the system tray clock didn't. So I rebooted, and it's now  correct. Didn't even have to remount the root filesystem!

I made sure that custom was in my feed list.
I typed:
Code: [Select]
ipkg update
ipkg install timeszones
I exited out of Match/open box.
typed:
Code: [Select]
ntpdate time.apple.com
startx
.. I seem to be good now.

I just updated the timezones package (timezones_2007_all.ipk) to fix some errors introduced by the know-it-all US government. The Australian Eastern Time Zone is called AET or AEST, NOT EST. Damn smart arses think they know better than us Australian what our timezone is called.

I would like to have the timezone show my city name, not some other city many miles away.
I tried copying a city in my time zone to another location, renaming it, and copying it back, but it doesn't show up in the pick list of available cities in City Time.
I can't figure out what else I have to do.
Or isn't it even possible?
My specs are in my sig.

I was here just finishing installing the cacko 1.23 on a c-3200 and then it hit me.  The daylight saving time problem ws screwing me up.  I downloaded the ipk fix and installed it with no terminal usage.  I rebooted and everything works just fine.  thanks guys!
