When you try to create a talk using Chrome, the time-picker doens't update the input field if the hour is single digit (e.g. 9:00, 8:30 etc).
The console throws the following warning:
""The specified value "9:15" does not conform to the required format. The format is "HH:mm", "HH:mm:ss" or "HH:mm:ss.SSS" where HH is 00-23, mm is 00-59, ss is 00-59, and SSS is 000-999.""
If the hour is a double digit hour (10, 11 etc), it works fine.
Works even with a single digit hour in Firefox
