Description:
------------
The PECL package that adds support for Paradox database tables to PHP does not correctly address the Paradox PX_FIELD_TIMESTAMP format.  The included method px_timestamp2str(), does not return an accurate representation of the timestamp.  Additionally, the description of PX_FIELD_TIMESTAMP is incorrect.  I understand the developer of this extension doesn't intend for it to ever progress past an experimental project.  Would you please update the documentation with these corrections?

Paradox timestamps are the number of milliseconds since 0001-01-01 (or practically, 0001-01-02 as they seem to start counting at the end of January 1st, 1 AD.  Note that there was no 0 AD)  The px_timestamp2str() method does not seem to function properly when converting the timestamp, providing a date that is off by one day, and a time that always defaults to an incorrect time.  Instead you can use the following calculation to convert PX_FIELD_TIMESTAMP to a unix timestamp:

$unixtime = ($record["timestamp"] / 1000) - (719163 * 86400)

Reproduce code:
---------------
px_timestamp2str($pxdoc,63385727274000,"Y-m-d H:i") 

Expected result:
----------------
should return "2009-08-11 9:27" or 1250044074 unix timestamp.


Actual result:
--------------
2009-08-12 -3:-14
