Why would we need to duplicate existing timezones? Our country has only two real timezones (+5 and +6). People in Qostanay oblast can just switch to +5 (Asia/Aqtobe).Per the theory.html file, our guideline is to split zones where timezone history has diverged at any point since 1970. Paul mentioned the details a few days ago at https://mm.icann.org/pipermail/tz/2018-December/027319.html--
