### Method

# GLib TimeZone find_interval

since: 2.26

#### Declaration

    gint
    g_time_zone_find_interval (
      GTimeZone* tz,
      GTimeType type,
      gint64 time_
    )

#### Description

Finds an interval within `tz` that corresponds to the given `time_`. The meaning of `time_` depends on `type`.

If `type` is `G_TIME_TYPE_UNIVERSAL` then this function will always succeed (since universal time is monotonic and continuous).

Otherwise `time_` is treated as local time. The distinction between `G_TIME_TYPE_STANDARD` and `G_TIME_TYPE_DAYLIGHT` is ignored except in the case that the given `time_` is ambiguous. In Toronto, for example, 01:30 on November 7th 2010 occurred twice (once inside of daylight savings time and the next, an hour later, outside of daylight savings time). In this case, the different value of `type` would result in a different interval being returned.

It is still possible for this function to fail. In Toronto, for example, 02:00 on March 14th 2010 does not exist (due to the leap forward to begin daylight savings time). -1 is returned in that case.

Available since: 2.26

#### Parameters

`type`

  Type: `GTimeType`

  The `GTimeType` of `time_`

`time_`

  Type: `gint64`

  A number of seconds since January 1, 1970

#### Return value

Type: `gint`

The interval containing `time_`, or -1 in case of failure.
