Symptom
You created a Extension Field with type Time after adding the field to the screen you can notice that the field has a default value even though you didn't specify it during the creation of the field.
Cause
The cause of this behavior is that a field with type Time cannot exist without a default starting time hence when it is created by default the system specify either 00:00 or 12:00 depending of your time zone settings in the system.
Resolution
The solution to this issue is under investigation.
