I am having the same problem and I did not want to have to remember to add 12:00 or teach others to do it.
I found 4 locations that had
JText::_('DATE_FORMAT_LC3')); and I added '$offset' So the line looks like
JText::_('DATE_FORMAT_LC3'), '$offset'); I got '$offset' from the time zone variable in configuration.php.

My host uses UTC for their servers. I have tested at (-8) Pacific and (+2) Jerusalem with study times from 00:00:00 to 23:59:59 and all areas are working correctly now.
I hope this helps.
Jesus Loves You.
