STD.Date.AdjustDate( date , [year_delta],[month_delta] ,[day_delta] )
| date | A date value in the Date_t format. |
| year_delta | The minimum acceptable year. Optional; defaults to zero. |
| month_delta | The minimum acceptable year. Optional; defaults to zero. |
| day_delta | The maximum acceptable year. Optional; defaults to zero. |
| Return: | AdjustDate returns date_t representing the adjusted date. |
The AdjustDate function adjusts a date by incrementing or decrementing year, month, and/or day values. The date must be in the Gregorian calendar after the year 1600.
If the new calculated date is invalid then it is normalized according to mktime() rules. For example, 20140130 plus 1 month would be 20140302.
Example:
IMPORT std; inDate :=19631123; Std.Date.AdjustDate(inDate,5,1,3); //returns 19681226
