===== Description =====
The **static** function ''unixTimeStamp()'' Parses the timestamp string **$str** and returns it in UNIX ''mktime'' format (.g. a number indicating the seconds after January 1st, 1970. 

It expects the date passed to be in one of the following formats:
  * "Y-m-d, H:i:s" (1970-12-24, 00:00:00) 
  * "Y-m-d H:i:s" (1970-12-24 00:00:00)
  * "YmdHis" (19701225000000) 
  * "M d Y h:i:s" (Dec 25 1970 00:00:00AM) (SQL Server and Sybase only) (the 3 letter month strings are controlled by a global array, which might need localisation).

For databases that do not support the functionality, the function makes use of ADOdb time handling library.

===== Usage =====
==== SQL Server example ====
<code php>
/*
 * Connection to SQL Server database assumed
 */
$d = $db::unixDate(strtotime('1920-10-10 00:00:00'));
print $d;
/*
 * returns -1553450400
 */
print date('Y-m-d',$d);
/*
 * Returns the following string: '1920-10-10'
 */
