Date problem ?

[Stan-librarian]

Hi,

Thanks for sharing this class.
I'm trying to use it against a Bibliomondo Portfolio ILS.

I succeeded in getting patron information et recording checkin and checkout.
However, while checkin I get an error which doesn't block the checkin "Notice: A non well formed numeric value encountered in sip2.class.php on line 738"

I'm providing the function an item number and a return date generated as follows :
$returnDate = date("Ymd His"); e.g. 20171122 174528
but the string generated is
09N20171122 17452819700822 120522APJL|AOJL|AB00000000429765|AC|AY0AZEF4B
so the return date used doesn't seem to be the one I want
It looks like my return date is used in field "transaction date" and the field return date contains "19700822 120522", which is very strange...

Thanks for your help.

PS : the line 738 is :
return date('Ymd His', $timestamp);
in function _datestamp($timestamp = '')
