Description

This problem occurs when editing a object, in the admin, in a popup window. For example object A has a reference to object B, while editing object A I create a new object B by clicking on the green plus. Now I have a popup with object B.

When the first field is a date field the top of the calendar widget disappears. The problem is in the openCaledar function, the widget is moved up for 75px but there is no checked if this will give a negative position. The openClock function has the same calculation, probably this problem doesn't occur as quick for the clock because it is smaller.

The following patch will fix this problem for the calendar and clock widget.
