My box is running R5D1 and I was wondering if it knew about the DST changes. Some posts suggested that newer builds should be OK. The tables all date 8/25/2005. Some Googling suggesting a way to read the tables. I did it against the 2 tables that look like they could apply to the EST zone:

root@mythtv:~# zdump -v /usr/share/zoneinfo/US/Eastern | grep 2007
/usr/share/zoneinfo/US/Eastern Sun Apr 1 06:59:59 2007 UTC = Sun Apr 1 01:59:59 2007 EST isdst=0 gmtoff=-18000
/usr/share/zoneinfo/US/Eastern Sun Apr 1 07:00:00 2007 UTC = Sun Apr 1 03:00:00 2007 EDT isdst=1 gmtoff=-14400
/usr/share/zoneinfo/US/Eastern Sun Oct 28 05:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 EDT isdst=1 gmtoff=-14400
/usr/share/zoneinfo/US/Eastern Sun Oct 28 06:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 EST isdst=0 gmtoff=-18000

root@mythtv:~# zdump -v /usr/share/zoneinfo/est5edt | grep 2007
/usr/share/zoneinfo/est5edt Sun Apr 1 06:59:59 2007 UTC = Sun Apr 1 01:59:59 2007 /usr/share/zoneinfo/est isdst=0 gmtoff=-18000
/usr/share/zoneinfo/est5edt Sun Apr 1 07:00:00 2007 UTC = Sun Apr 1 03:00:00 2007 edt isdst=1 gmtoff=-14400
/usr/share/zoneinfo/est5edt Sun Oct 28 05:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 edt isdst=1 gmtoff=-14400
/usr/share/zoneinfo/est5edt Sun Oct 28 06:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 /usr/share/zoneinfo/est isdst=0 gmtoff=-18000

The above seems to show that it doesn't have the updated schedule for 2007.

I guess next is figuring out how to update the tables.

FWIW, R5E50 gives me updated results:

I see that the timezones are in the C library "libc6" . I did an apt-get update and tried to update libc6 and it told me it is already the newest.


Then I read there is a tzdata package. I tried to install it but it couldn't find it:

Does anyone have any suggestions?

I followed the instructions here and it seems to have fixed my master backend.

Guess we'll know on March 11th...

To follow up on my own question I found this on the MythTV list. It seems the trick was getting the tzdata package manually. I installed it and when I checked it has the right tz info for 2007.

Worked like a charm, George. Thanks (you should make this into a short howto).

Looks like that file no longer exsist... ah, they changed it to tzdata_2007a-3_all.deb now. I'll post this in the howto section.

Posting to this thread for 2 reasons:
1) to "mod up" the thread so it's highly visible the day before the change
2) to update the name of the tzdata file; it has changed again to "tzdata_2007b-1_all.deb"

This works for R5D1:


Use the "zdump" command given earlier in this thread to verify that the change has been successful.

I don't know where the above-referenced "howto" is located; perhaps it has already been updated to be current. (I'm on dial-up, so only did a limited search for it.)

Cheers,

The howto is located here and was updated a while back when they changed the file name. Thanks for updating this thread as well.

thanks all for this! worked great. -c is the current version at this time for what it's worth.

Note, side happy note. Thanks to knoppmyth I've gotten good enough at linux to move my company from ms-sql and asp to mySQL and php. It's Ubuntu as opposed to knopp but it's not MS and I'm happy at the money I am saving.

Thanks all for that as well!
