The data objects of the date types, time types, and time stamp types are used to store calendar dates, times, and time stamps.


Type Length Standard Length Meaning Data Object
d 8 characters   Date type Date field
t 6 characters   Time type Time field
utclong 8 byte   Time stamp type Time stamp field

Value Ranges and Initial Values

Type Value Range Initial Value
d Any eight Unicode characters that can be encoded in UCS-2; valid values are only digits 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 Unicode characters that can be encoded in UCS-2; valid values are only digits that are valid as times in accordance with the 24-hour clock range in the format hhmmss. hh (hours): 00 to 23, mm (minutes): 00 to 59, ss (seconds): 00 to 59. 000000
utclong Internal 8-byte integer representation of a UTC time stamp exact to 100 nanoseconds, in ISO-8601 notation between 0001-01-01T00:00:00.0000000 and 9999-12-31T23:59:59.9999999. There are 3,155,380,704,000,000,000 real values and one special initial value. 0



Declaration of date fields and time fields of the built-in ABAP types d and t and examples for their use. The declarations are made with the statement DATA and using the declaration operator DATA.

DATA: tomorrow  TYPE d,
      next_hour TYPE t.

FINAL(today) = cl_demo_date_time=>get_user_date( ).
FINAL(now)   = cl_demo_date_time=>get_user_time( ).

tomorrow  = today + 1.
next_hour = ( now + 3600 ) / 3600 * 3600.


Creation of a time stamp of the type utclong with the built-in function utclong_current and its conversion to date and time fields.

FINAL(ts) = utclong_current( ).

FINAL(time_zone) = cl_demo_date_time=>get_user_time_zone( ).
        INTO DATE FINAL(dat) TIME FINAL(tim)
        TIME ZONE time_zone.

  |{ ts }\n| &&
  |{ dat }\n| &&
  |{ tim }|  ).
