[TYPO3-project-seminars] time changes when copying single seminars

[Andreas Siemer]

Hi,

we have a problem with starttime and endtime when copying single 
seminars from one file to another using the copy&paste function of typo3.
In the copied seminar starttime and endtime have been changed, f.e. 
instead 13:00 to 17:00 it is 11:00 to 15:00.

Can anyone explain/ reproduse this?
Versions: TYPO3 4.2.0 seminars 0.4.10

Thanks for your hints!

Andreas
