Sometime to short info requested in form only Date info are requested. In this case the date time file has time set as 00:00:00.

I found useful to replace this null time with current time, so if some date are entered the same day we can found correct cronology.

in save action of my table Autoletturekm for field DataIns, I added.

$this->objAutoletturekm->DataIns->setTime(date("H"),date("i"), date("s"));

note: to my limited knowledge, QDataTimePicker class refuse this setting ....

I suggest that in core is possible to add a similar functionality:
