I find this magic quite unpleasant. It causes a massive amount of confusion (eg if you write TZ=UTC+8, you actually get UTC-8, except it’s called UTC. You’d actually need to type eg TZ=XYZ-8 because you subtract 8 hours to get UTC. The theory at the time was that it made it easier to enter US timezones like UTC-5.) Furthermore, some applications won’t parse a timezone that isn’t in the local tzdb so you’d actually need to enter eg TZ=Etc/GMT-8 for UTC+8. And heaven forfend an application might parse TZ=UTC+8 in the “normal” way instead of the posix way. What a recipe for disaster. Encoding daylight savings in the env var just makes the whole mess worse. |
