Date and time conversions

The ABL DATE, DATETIME, and DATETIME-TZ data types are all mapped to the java.util.GregorianCalendar class. This class supports all the necessary functionality for these data types (it supports date, time, and time zone data). The Java Open Client processes the data differently based on the ABL data type, as shown in the following table.
