* @category Time Zone Helpers
|

|
|
* @summary Gets the offset in milliseconds between the time zone and Universal Coordinated Time (UTC)
|
||
|
|
*
|
||
|
|
* @description
|
||
|
|
* Returns the time zone offset from UTC time in milliseconds for IANA time zones as well
|
||
|
|
* as other time zone offset string formats.
|
||
|
|
*
|
||
|
|
* For time zones where daylight savings time is applicable a `Date` should be passed on
|
||
|
|
* the second parameter to ensure the offset correctly accounts for DST at that time of
|
||
|
|
* year. When omitted, the current date is used.
|
||
|
|
*
|
||
|
|
* @param timeZone the time zone of this local time, can be an offset or IANA time zone
|
||
|
|
* @param date the date with values representing the local time
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* const result = getTimezoneOffset('-07:00')
|
||
|
|
* //=> -18000000 (-7 * 60 * 60 * 1000)
|
||
|
|
* const result = getTimezoneOffset('Africa/Johannesburg')
|
||
|
|
* //=> 7200000 (2 * 60 * 60 * 1000)
|
||
|
|
* const result = getTimezoneOffset('America/New_York', new Date(2016, 0, 1))
|
||
|
|
* //=> -18000000 (-5 * 60 * 60 * 1000)
|
||
|
|
* const result = getTimezoneOffset('America/New_York', new Date(2016, 6, 1))
|

|
|
* //=> -14400000 (-4 * 60 * 60 * 1000)
