I'm using Ubuntu 12.10.

In review on toaster/master.

Fix merged to master:

http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=af32d95f3beeb678fb59436445237efe53a36726

Verified on both:

It happened on my Ubuntu 12.10 system with the following error:

This might be of interest:

It could be that we need to have some more intelligent code setting this value.

TIME_ZONE is supposed to be like the default for Django 'America/Chicago', but the time.tzname(0) or (1) returns 'CST' or 'CDT', clearly not correct.

I found the following to get a timezone string like above. 

@@ -51,8 +51,9 @@ ALLOWED_HOSTS = []
 # In a Windows environment this must be set to your system time zone.

 # Always use local computer's time zone
-import time
-TIME_ZONE = time.tzname[0]
+import pytz # $pip install pytz
+from tzlocal import get_localzone # $ pip install tzlocal
+TIME_ZONE = str(get_localzone())

Testing it now with a build so I can examine the build time.

The fix in my last comment works on ubuntu 12.04 based on examination of a new build's completion time on the All Builds screen.

Patch available on bitbake-devel mailing list, due to the High/Critical importance of this bug.

I hear you, thanks for the input on various configurations.

Please do not submit this patch, I'll come back with a v2.


Ross, I tried time.tzname (as it currently stands) and it doesn't provide a /usr/share/zoneinfo/ compatible name :(.

You say that, but the Fedora 20 install I have here (a) doesn't have TZ and
(b) has /etc/localtime -> ../usr/share/zoneinfo/Europe/London. On my CentOS
6.5 machine (possibly irrelevant for Toaster, but...) TZ is also unset but
/etc/localtime is just a plain copy of some timezone file rather than a
symlink. Older RH-style systems such as CentOS 6 have a ZONE value in
/etc/sysconfig/clock but Fedora appears to have eliminated this file.

Given that, I don't think this is a complete fix.

Cheers,

New patch sent to bitbake-devel and toaster mailing lists.

We reverse-match /etc/localtime into /usr/share/zoneinfo/ if the TZ is not set.

Demoting this from High since the critical issue was resolved.

This is verified.
