Questions tagged [timezone]

When using or applying a TZ value.

Each place on earth has a local time, that local time is set by the value of the timezone used relative to the Zero time (UTC). There are more than 500 localtimes (zones that keep the same local time) but only about 40 Time Zones (some countries use 30 minutes offsets).

Why does TZ=UTC-8 produce dates that are UTC+8?

The current time in Los Angeles is 18:05. But when I run TZ=UTC-8 date --iso=ns, I get: 2013-12-07T10:05:37,788173835+0800 The date utility tells me that the time is 10:05, and even says that it's reporting it as UTC+8. Why?

Why is `TZ=Asia/Kolkata date --date="1/1/1906"` invalid?
