All Implemented Interfaces:

Function, Operation, Serializable

public class DateFormatter
extends DateOperation
implements Function

Class DateFormatter is used to convert a date timestamp to a formatted string, where a timestamp is the number of milliseconds since January 1, 1970, 00:00:00 GMT, using the SimpleDateFormat syntax.

Note the timezone data is given to the SimpleDateFormat, not the internal Calendar instance which interprets the 'timestamp' value as it is assumed the timestamp is already in GMT.
