/**

* The function extracts UTC offset in minutes from the given date in specified

|
|
* Unlike `Date.prototype.getTimezoneOffset`, this function returns the value
|
|
* mirrored to the sign of the offset in the time zone. For Asia/Singapore
|
|
* (UTC+8), `tzOffset` returns 480, while `getTimezoneOffset` returns -480.
|

*
|
|
* @param timeZone - Time zone name (IANA or UTC offset)
|
|
* @param date - Date to check the offset for
|
|
*
|
|
* @returns UTC offset in minutes
