The DATETIME and DATETIME-TZ data types are also new to OpenEdge Release 10. These two ABL data types provide the following benefits (where datetime refers to DATETIME or DATETIME-TZ):
You no longer have to manipulate dates and times separately to have datetime types of data.
If you use DataServers, you can get direct mapping to their datetime data.
If you do open ABL programming, you can convert your datetime data directly.
