The ToDateTime method is useful because it can convert any date in the current calendar to a Gregorian calendar date. The Gregorian date can subsequently be used, for example, to compare dates in different calendars or create an equivalent date in a particular calendar.

Notes to Inheritors:

The derived class must support CurrentEra when it is passed as the era parameter. One way to support CurrentEra is by replacing it with the value stored in the first element of the Eras property array, which is the value for the current era of the calendar.
