Data Types in ABAP Release 7.54

Modification

New Built-In ABAP Type utclong

The new built-in time stamp type utclong makes it possible to declare time stamp fields. The new data type is taken into account in all relevant positions. Important points are:

The associated data type in ABAP Dictionary was introduced with the name UTCLONG.
The value range of the new data type are time stamps between 0001-01-01T00:00:00.0000000 and 9999-12-31T23:59:59.9999999 plus a special initial value.
In assignments and comparisons, the data type utclong can only be converted to the types c and string, and vice versa. In assignments, any attempt to perform another conversion raises an exception of the new class CX_SY_CONVERSION_NOT_SUPPORTED.
Time stamp fields are formatted specially in string templates or using the statement WRITE TO.
There is a mapping rule for asXML.

Time stamp fields must meet an alignment requirement. Their memory address must be divisible by eight.
