+===== Description =====
+This function extends the adodb_date() function, allowing the second argument to be passed as an ISO format string instead of a timestamp. This makes it easier to generate formatted times outside of the normal unix timestamp range.
+----------------------------------
 ===== Usage =====
 <code php>
 $d = adodb_date2('d-M-Y H:i','1520-12-25 13:01:34');
 </code>
+===== Note =====
+To make the calculation work correctly for early years, it is important to use 4 digit years for the ''$isoDateString''
