* #GTimeZone is a structure that represents a time zone, at no
* particular point in time. It is refcounted and immutable.
*
- * A time zone contains a number of intervals. Each interval has
- * an abbreviation to describe it, an offet to UTC and a flag indicating
- * if the daylight savings time is in effect during that interval. A
- * time zone always has at least one interval -- interval 0.
- *
- * Every UTC time is contained within exactly one interval, but a given
- * local time may be contained within zero, one or two intervals (due to
- * incontinuities associated with daylight savings time).
- *
- * An interval may refer to a specific period of time (eg: the duration
- * of daylight savings time during 2010) or it may refer to many periods
- * of time that share the same properties (eg: all periods of daylight
- * savings time). It is also possible (usually for political reasons)
- * that some properties (like the abbreviation) change between intervals
- * without other properties changing.
- *
* #GTimeZone is available since GLib 2.26.
