[netCDFJava #JDB-235822]: Fwd: non-standard calendars in the IDV

Hi Don:

Theres no way to make java.util.Date do the right thing for non-standard 
calendars.
You have to use CoordinateAxis1DTime.getCalendarDates().
I am adding a deprecation on CalendarDate.toDate() to emphasize this.
Thanks for reporting.

John
