Howdy!

Looking at the zone.tab file I can see a few timezones that, although valid in the past, they are not valid anymore. I can pick as example, reported on the GNOME Bugzilla[0], Asia/Novosibirsk, that used to be UTC+7, but nowadays is considered the same one than Asia/Almaty, which one is UTC+6.

How is the rule about keep or remove these not-used-anymore timezones?
Would you guys accept a patch removing the not-used-anymore ones?
What kind of information should I provide/get to be sure that one timezone could be removed?

Thanks is advance and Best Regards.
