Expand description

Timezone offset name information.

This trait exposes display names that describe an offset in various situations.

use chrono::{Duration, Offset, TimeZone};
use chrono_tz::Europe::London;
use chrono_tz::OffsetName;

let london_time = London.ymd(2016, 2, 10).and_hms(12, 0, 0);
assert_eq!(london_time.offset().tz_id(), "Europe/London");
// London is normally on GMT
assert_eq!(london_time.offset().abbreviation(), "GMT");

let london_summer_time = London.ymd(2016, 5, 10).and_hms(12, 0, 0);
// The TZ ID remains constant year round
assert_eq!(london_summer_time.offset().tz_id(), "Europe/London");
// During the summer, this becomes British Summer Time
assert_eq!(london_summer_time.offset().abbreviation(), "BST");

Required Methods

The IANA TZDB identifier (ex: America/New_York)

The abbreviation to use in a longer timestamp (ex: EST)

This takes into account any special offsets that may be in effect. For example, at a given instant, the time zone with ID America/New_York may be either EST or EDT.
