getProlepticGregorianCalendarUTC

public static Calendar getProlepticGregorianCalendarUTC()

TODO - this is a temporary fix for handling Julian calendar dates. Returns a Gregorian calendar that can be used from year 0+ instead of default 1582.10.15. This is desirable for some UDFs that work on dates which normally would use Julian calendar.

Returns:

the calendar
