The conceptual data items DATE, DAY, DAY-OF-WEEK, and TIME implicitly have
USAGE DISPLAY.
- DATE (Without the YYYYMMDD Phrase)
- Has the implicit PICTURE 9(6).
The sequence of data elements (from
left to right) is:
2 digits for year of century
2 digits for month of year
2 digits for day of month
Thus, 16 November 1963 is expressed
as:
631116
IBM Extension
- DATE (With the YYYYMMDD Phrase)
- Has the implicit PICTURE 9(8).
The sequence of data elements (from
left to right) is:
4 digits for year in the Gregorian calendar
2 digits for month of year
2 digits for day of month
Thus, 16 November 1963 is expressed
as:
19631116
End of IBM Extension
- DAY (Without the YYYYDDD Phrase)
- Has the implicit PICTURE 9(5).
The sequence of data elements (from
left to right) is:
2 digits for year of century
3 digits for day of year
Thus 25 December 1988 is expressed as:
88360
IBM Extension
- DAY (With the YYYYDDD Phrase)
- Has the implicit PICTURE 9(7).
The sequence of data elements (from
left to right) is:
4 digits for year in the Gregorian calendar
3 digits for day of year
Thus, 31 December 1995 is expressed as:
1995365
End of IBM Extension
- DAY-OF-WEEK
- Has the implicit PICTURE 9(1).
The single data element represents
the day of the week thus:
1 represents Monday
2 represents Tuesday
3 represents Wednesday
4 represents Thursday
5 represents Friday
6 represents Saturday
7 represents Sunday
Thus Thursday is expressed as: 4
- TIME
- Has the implicit PICTURE 9(8).
The sequence of data elements (from
left to right) is:
2 digits for hour of day
2 digits for minute of hour
2 digits for second of minute
2 digits for hundredths of second
Thus 12.25 seconds after 2:41
PM is expressed as:
14411225
