+ * @name getTimezoneOffset
+ * @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 {String} timeZone - the time zone of this local time, can be an offset or IANA time zone
+ * @param {Date|Number} [date] - the date with values representing the local time
+ * @returns {Number} the time zone offset in milliseconds
+ *
+ * @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)
