## Description

A timezone.

Timezones are global to the GWeather world (as obtained by `gweather_location_get_world()`); they can be gotten by passing `gweather_timezone_get_by_tzid()` with a tzid like "America/New_York" or "Europe/London".

## Functions

### gweather_timezone_get_type ()

    GType
    gweather_timezone_get_type (void);

### GWEATHER_TYPE_TIMEZONE

    #define GWEATHER_TYPE_TIMEZONE (gweather_timezone_get_type ())

### gweather_timezone_get_name ()

    const char *
    gweather_timezone_get_name (GWeatherTimezone *zone);

Gets `zone` 's name; a translated, user-presentable string.

Note that the returned name might not be unique among timezones, and may not make sense to the user unless it is presented along with the timezone's country's name (or in some context where the country is obvious).

#### Parameters

zone | a GWeatherTimezone |

#### Returns

`zone` 's name

### gweather_timezone_get_tzid ()

    const char *
    gweather_timezone_get_tzid (GWeatherTimezone *zone);

Gets `zone` 's tzdata identifier, eg "America/New_York".

#### Parameters

zone | a GWeatherTimezone |

#### Returns

`zone` 's tzid

### gweather_timezone_get_by_tzid ()

    GWeatherTimezone *
    gweather_timezone_get_by_tzid (const char *tzid);

Get the GWeatherTimezone for `tzid` .

#### Parameters

tzid | A timezone identifier, like "America/New_York" or "Europe/London" |

#### Returns

A GWeatherTimezone. This object belongs to GWeather, do not unref it.

### gweather_timezone_get_offset ()

    int
    gweather_timezone_get_offset (GWeatherTimezone *zone);

Gets `zone` 's standard offset from UTC, in minutes. Eg, a value of 120 would indicate "GMT+2".

#### Parameters

zone | a GWeatherTimezone |

#### Returns

`zone` 's standard offset, in minutes

### gweather_timezone_has_dst ()

    gboolean
    gweather_timezone_has_dst (GWeatherTimezone *zone);

Checks if `zone` observes daylight/summer time for part of the year.

#### Parameters

zone | a GWeatherTimezone |

#### Returns

`TRUE` if `zone` observes daylight/summer time.

### gweather_timezone_get_dst_offset ()

    int
    gweather_timezone_get_dst_offset (GWeatherTimezone *zone);

Gets `zone` 's daylight/summer time offset from UTC, in minutes. Eg, a value of 120 would indicate "GMT+2". This is only meaningful if `gweather_timezone_has_dst()` returns `TRUE`.

#### Parameters

zone | a GWeatherTimezone |

#### Returns

`zone` 's daylight/summer time offset, in minutes

### gweather_timezone_ref ()

    GWeatherTimezone *
    gweather_timezone_ref (GWeatherTimezone *zone);

Adds 1 to `zone` 's reference count.

#### Parameters

zone | a GWeatherTimezone |

#### Returns

`zone`

### gweather_timezone_unref ()

    void
    gweather_timezone_unref (GWeatherTimezone *zone);

Subtracts 1 from `zone` 's reference count and frees it if it reaches 0.

#### Parameters

zone | a GWeatherTimezone |

### gweather_timezone_get_utc ()

    GWeatherTimezone *
    gweather_timezone_get_utc (void);

Gets the UTC timezone.

#### Returns

a GWeatherTimezone for UTC, or `NULL` on error.

## Types and Values
