Bug Description:
RFE: Add ability to use SpinnerDateModel with different TimeZones and Locales

Currently SpinnerDateModel calls Calendar.getInstance() to create its Calendars.
We need to be able to specify a different TimeZone and Locale than the defaults returned by TimeZone.getDefault() and Locale.getDefault(), to be used when getting the Calendar instance.
Note our users can use one Locale for Currencies and another for Dates so changing the Default Locale is not a viable solution for us.
