How do I convert a Timestamp to a Calendar?

[keith tyson]

I have a method that returns a Timestamp and I need to pass this to a method that is expecting a Calendar object.
ie.
deliveryDetails.getWindowStart() // returns a Timestamp
and I need to pass another method this value as a Calendar.

Hi Keith,
Since Timestamp is a subclass of Date, the following should work:
GregorianCalendar gc = new GregorianCalendar();
gc.setTime( deliveryDetails.getWindowStart() );
newMethod( gc );
Regards,
Manfred.
