Timezone / DST reference in DFF Value Set

There is a profile option called "Client Timezone" which considers the DST in Canada and USA.

Is there a way to reference the table and field supporting that client timezone into a Value Set inside a DFF?

The objective is to set a DFF in the Organization parameters form where we would set the timezone the organization belongs to. Obviously, we need to consider the DST, otherwise the organizations time will be one hour offset during the extended DST period.

Thanks
