Predefined Date Types and Time Types

The data objects of the date types and time types are used to add calendar dates and times.

Attributes

Type	Length	Standard Length	Name
d	8 characters		Date field
t	6 characters		Time field

Value Ranges and Initial Values

d	Any eight alphanumeric characters; only those digits are valid, however, that are valid as dates in accordance with the calendar rules in the format "yyyymmdd": "yyyy" (year): 0001 to 9999, "mm" (month): 01 to 12, "dd" (day): 01 to 31	"00000000"
t	Any six alphanumeric characters; only those digits are valid, however, that are valid as times in accordance in the format 24-hour clock format "hhmmss". "hh" (hours): 00 to 23, "mm" (minutes): 00 to 59, "ss" (seconds): 00 to 59.	"000000"

Notes

The date types and time types are used to handle values for calendar dates and times. Information about how they are used and their special handling can be found under Date Fields and Time Fields.

From a technical perspective, the data types d and t are flat character-like types. The content of their data objects is saved in accordance with the current system code page.

As character-like data types, data objects of the data types d and t can be used like text fields of the type c. This applies in particular also to structures with components of the types d and t.

The generic type clike also covers the types d and t.

Data objects of the types d and t display character-like behavior in character-like operand positions and numeric behavior in numeric operand positions.

The data types d and t are the predefined ABAP types that correspond to the special types DATS and TIMS in ABAP Dictionary.

The valid values of the data types d and t are a subset of their value range. ABAP statements that work with data objects of these types are only guaranteed to function correctly for operands with valid values.
