Cannot enter event time in Calendar 6.0

I recently updgraded to Mountain Lion, and when I try to enter a new event into Calendar (by double clicking on day, week or month and unchecking all day option), there is no option to enter the specific event time.

Also, Calendar is randomnly changing the time of events of synced google calendar events to 19:45.

Anyone else experience this problem. Suggestions as how to fix these two problems would be greatly appreciated.

Thank you.
