Date and Time System Variables

This document covers the following topics:


Usage

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.

*DAT* - Date System Variables

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

*TIM* - Time System Variables

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 SETTIME statement was executed (in format HHIISST (*)).

(r) represents the statement label or source-code line number of the SETTIME statement used as the basis for *TIMD.

*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).

*TIME-OUT is 0 if transaction mode has not been entered. Transaction mode is entered with the execution of a FIND, READ or GET statement that reads a database record for the purpose of updating or deleting the record.

*TIME-OUT is reset to 0 when an END TRANSACTION or BACKOUT TRANSACTION statement is executed.

*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.
