This document covers the following topics:
The date and time system variables listed below may be specified in the following places:
The contents of date and time system variables as generated by Natural are non-modifiable, which means that in a Natural program you cannot assign another value to any of them.
All date system variables contain the current date. The format of the date is different for each date variable, as indicated below.
| Date Variable | Format/Length | Date Format* |
|---|---|---|
| *DATD | A8 | DD.MM.YY |
| *DAT4D | A10 | DD.MM.YYYY |
| *DATE | A8 | DD/MM/YY |
| *DAT4E | A10 | DD/MM/YYYY |
| *DATG | A15 | DDmonthnameYYYY (Gregorian date) |
| *DATI | A8 | YY-MM-DD |
| *DAT4I | A10 | YYYY-MM-DD |
| *DATJ | A5 | YYDDD (Julian date) |
| *DAT4J | A7 | YYYYDDD (Julian date) |
| *DATN | N8 | YYYYMMDD |
| *DATU | A8 | MM/DD/YY |
| *DAT4U | A10 | MM/DD/YYYY |
| *DATV | A11 | DD-MON-YYYY |
| *DATVS | A9 | DDMONYYYY |
| *DATX | D | internal date format |
* D = day, M = month, Y = year, MON = leading three bytes of
the month's name as in *DATG
At runtime, the content of a time system variable is evaluated anew each time the variable is referenced in a Natural program. The format of the time is different for each time variable, as indicated below.
| Time Variable | Format/Length | Explanation |
|---|---|---|
| *TIMD (r) | N7 | Can only be used in conjunction with a previous
SETTIME statement.
Contains the time that has elapsed after the |
| *TIME | A10 | Contains the time of day in format HH:II:SS.T (*). |
| *TIME-OUT | N5 | Contains the number of seconds remaining before the current
transaction will be timed out (only available with Natural Security).
|
| *TIMESTMP | B8 |
Machine-internal store clock value. |
| *TIMN | N7 | Contains the time of day in format HHIISST (*). |
| *TIMX | T | Contains the time of day in internal time format. |
* H = hour, I = minute, S = second, T = tenth of a second.
