$Sir_ND2Date
Convert datetime number of days to string
Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for this $function is DaysToString.
The $Sir_ND2Date function expects a numeric datetime argument containing a number of days since January 1, 1900, and a datetime format string. It returns the date represented by the first argument, in the format corresponding to the second argument. $Sir_ND2Date accepts an optional error control string and returns the null string if an error is detected.
Syntax
%dat = $Sir_ND2Date(datn, fmt, errctl)
Syntax terms
| %dat | Set to the datetime value string, using format specified by fmt, corresponding to datn, unless an error is detected. |
|---|---|
| datn | Datetime number containing a signed number of days since January 1, 1900. |

Usage notes
