Module chrono::offset

The time zone, which calculates offsets from the local time to UTC.

There are three operations provided by the TimeZone trait:

1. Converting the local NaiveDateTime to DateTime<Tz>
2. Converting the UTC NaiveDateTime to DateTime<Tz>
3. Converting DateTime<Tz> to the local NaiveDateTime

1 is used for constructors. 2 is used for the with_timezone method of date and time types. 3 is used for other methods, e.g. year() or format(), and provided by an associated type which implements Offset (which then passed to TimeZone for actual implementations). Technically speaking TimeZone has a total knowledge about given timescale, but Offset is used as a cache to avoid the repeated conversion and provides implementations for 1 and 3. An TimeZone instance can be reconstructed from the corresponding Offset instance.

Enums

LocalResult
