Class TzdbZone1970Location

A location entry generated from the "zone1970.tab" file in a TZDB release. This can be used to provide users with a choice of time zone, although it is not internationalized. This is equivalent to TzdbZoneLocation, except that multiple countries may be represented.

Availability net45, netstandard1.3

Declaration

public TzdbZone1970Location(int latitudeSeconds, int longitudeSeconds, IEnumerable<TzdbZone1970Location.Country> countries, string zoneId, string comment)

Parameters

Type	Name	Description
Int32	latitudeSeconds	Latitude of the location, in seconds.
Int32	longitudeSeconds	Longitude of the location, in seconds.
IEnumerable<TzdbZone1970Location.Country>	countries	Countries associated with this location. Must not be null, must have at least one entry, and all entries must be non-null.
String	zoneId	Time zone identifier of the location. Must not be null.
String	comment	Optional comment. Must not be null, but may be empty.

Remarks

This constructor is only public for the sake of testability. Non-test code should usually obtain locations from a TzdbDateTimeZoneSource.

Exceptions

Type	Condition
ArgumentOutOfRangeException	The latitude or longitude is invalid.
ArgumentNullException	countries, zoneId or comment is null

Properties

Comment

Gets the comment (in English) for the mapping, if any.

Since 2.0.x

Availability net45, netstandard1.3

Declaration

public string Comment { get; }

Property Value

Type	Description
String	The comment (in English) for the mapping, if any. (The value returned is never null.)

Remarks

This is usually used to differentiate between locations in the same country. This will return an empty string if no comment was provided in the original data.

Countries

Gets the list of countries associated with this location.

Since 2.0.x

Availability net45, netstandard1.3

Declaration

public IList<TzdbZone1970Location.Country> Countries { get; }

Property Value

Type	Description
IList<TzdbZone1970Location.Country>	The list of countries associated with this location (The value returned is never null.)

Remarks

The list is immutable, and will always contain at least one entry. The list is in the order specified in "zone1970.tab", so the first entry is always the country containing the position indicated by the latitude and longitude, and is the most populous country in the list. No entry in this list is ever null.

Latitude

Gets the latitude in degrees; positive for North, negative for South.

Since 2.0.x

Availability net45, netstandard1.3

Declaration

public double Latitude { get; }

Since 2.0.x

Availability net45, netstandard1.3

Declaration

public string ZoneId { get; }

Property Value
