Excerpts from James Cameron's message of Mon Mar 21 04:09:27 +0100 2011:

Thanks for the patch! It's a good start, but unfortunately not enough.
POSIX defines TZ as "std offset dst offset, rule" [1], with std and dst
being the name of the _local_ time zone (for standard resp. daylight
savings time). Even after your patch Sugar always claims the local time
zone to be UTC which is clearly incorrect (for non-zero offsets).

In the long term I'd like to get rid of this Sugar-specific control
panel and recycle something from Gnome.

Short term an option might be to parse the /usr/share/zoneinfo/zone.tab
file. Probably too invasive for 0.92.x, though (but OLPC can cherry-pick
from master).
