[atlas] measurment with endtime - faulty date

Some more persistence lead to the insight on how to reproduce the issue.

- Login
- measurements (you should see the list of 'my measurements'
- click on any of them which was a ping test.
- close the newly opened tab
- now try to set-up a new measurement with an end time and date.

Or alternatively for the last step: right click on any measurement in 
'my measurement' and change the end data or even the description.

This was reproducible on a ubuntu laptop with firefox but also on win7 
with chrome or firefox.

I hope others can reproduce.

By all these tests I found that logging out and back in solves the issue.

Thanks,

Dave
