Description of Problem:

When copying appointments while being in week view, the start time of the
copied event is set to midnight of the target day. 

The appointment duration remains, i.e. if the source event started at 4pm
and ended at 7pm, the copy event would start at 12pm and end at 3am.


Steps to reproduce the problem:

1. Create an event in week view.
2. Right-click on the created event and select "Copy".
3. Move the pointer into another day, left-click to activate this day, 
   right-click to open the context menu, and select "Paste".


How often does this happen? 

Always.
