```

### tzdataCoordinateRegex

Type: `RegExp`

It matches time zone coordinates in [tz database](https://www.iana.org/time-zones) format:

> Latitude and longitude of the zone's principal location in [ISO 6709](https://www.iso.org/iso/catalogue_detail.htm?csnumber=39242) sign-degrees-minutes-seconds format, either `+-DDMM+-DDDMM` or `+-DDMMSS+-DDDMMSS`, first latitude (`+` is north), then longitude (`+` is east).

```javascript

tzdataCoordinateRegex.exec('+4254-07436');

/*=> [

  '+4254-07436',

  '+',

  '42',

  '54',

  undefined,

  '-',

  '074',

  '36',

  undefined,

  index: 0,

  input: '+4254-07436',

  groups: {

    latitudeSeconds: undefined,

    longitudeSeconds: undefined

  }

] */

tzdataCoordinateRegex.exec('-353916+1394441');

/*=> [

  '-353916+1394441',

  '-',

  '35',

  '39',

  '16',

  '+',

  '139',

  '44',

  '41',

  index: 0,

  input: '-353916+1394441',

  groups: {

    latitudeSeconds: '16',

    longitudeSeconds: '41'

  }

] */
