$Sir ND2Date

<section begin="desc" />Convert datetime number of days to string<section end="desc" />

Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Sir_ND2Date function is to be entered.

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

<section begin="syntax" /> %dat = $Sir_ND2Date(datn, fmt, errctl) <section end="syntax" />
