# Server time zone IDs

Every value the server's `timezone` setting, the `HAMMER_TIMEZONE` environment variable, and
`TZ` accept. See [Time zone](HOW-TO-RUN-A-SERVER.md#time-zone) for what the setting does and
which one wins when more than one is set.

These are IANA (tz database) zone IDs, read from the JVM's own copy of the database, so the
same IDs work on every host regardless of what the operating system has installed. They are
case-sensitive: `Europe/Paris` is valid, `europe/paris` is not.

The offset columns are sampled mid-January and mid-July. Where they differ, the zone observes
daylight saving and the server follows the shift on its own.

Generated from the tz database shipped with JDK 21.0.9 (604 IDs). A JDK update can add or retire
entries; the authoritative list for a given install is always `ZoneId.getAvailableZoneIds()` on the
JDK the server runs on.

## Legacy and fixed-offset IDs

The tz database keeps these for backwards compatibility. Each is either an alias for a
`Region/City` zone or a fixed offset that never shifts, so prefer the `Region/City` form
above. `UTC` is the one worth using directly: it is the default, and the right choice when
you want timestamps to stay comparable across hosts.

The `Etc/GMT+N` IDs have **inverted** signs, a tz database quirk: `Etc/GMT+5` is five hours
*behind* UTC.
