Hi John,

What the error message means is that you need to first instantiate an
instance of the Calendar object, i.e.:

	Calendar cal = new Calendar();

This will create a Calendar object with the default time zone and
locale. To get the time zone offset, call the get() method by using the
Calendar object to access it and pass the static constant value for
ZONE_OFFSET to it, like:

	int zoneOffset = cal.get(Calendar.ZONE_OFFSET);

This will return the "raw offset from GMT in milliseconds" (according to
the API doc at
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Calendar.html#ZONE_OFF
SET .

Hope this helps!
