I've just seen a bug with TimeRanges, it is moving constantly down and down and in fact it shows wrong hours.
As an example I uploaded a photo of TimeRanges at the beggining of the day and next to it there is a foto with TimeRange moved slightly down. On selecting 1:00 it will show range 1:00-1:15, but on the second screen I wanted to select 16:00-16:15, but it shows 15:45-16:00. It is strange and I don't know what is wrong here.
<div id="daily" style="float:left; width:44%; margin-left:20px; display:block">
