Warning of date when integrating with module event calendar

Hi people,
Just want to know that I integrated Date module with the module Event Calendar and I got a warning when I was about to create a new event and the warning came from de module Date( specifically from date_api.module at line 710).

I only propose to add a small validation for make sure that and object is entering to get it's class name (avoid non objects values)

Line 710:
if ( get_class($date) != 'DateTime') {

Change to:
if ( is_object($date) && get_class($date) != 'DateTime') {

thanks for the time!!!
