Hi Bill,
You found a bug in the time formatting of the calendar! Thank you for reporting this.
It's surprising, this bug has been there for many years and until today nobody complained. Apparently not many calendar users are interested in leading zeros.
The problem can be solved by editing the file "common/toolbox.php" and replacing line 59 . . .
$phpFormat = str_replace(array('H','h','m'),array(($ampm ? 'h' : 'H'),($ampm ? 'g' : 'G'),'i'),$format);
by . . .
$phpFormat = str_replace(array('h','H','m'),array(($ampm ? 'g' : 'G'),($ampm ? 'h' : 'H'),'i'),$format);
I will change this for the next calendar version.
Roel
