I have a node type='event' that has a "text field with date popup calendar". The date format is "05/13/2015 - 7:02pm". On the edit page, the form renders as two fields: a calendar popup text field and a separate field for the time. This field is mandatory; but, it has been requested that the time value not be mandatory.
The problem occurs when the node is saved. It saves the date correctly; but, it inserts the current time if no time has been entered. Is there a way to have it not enter a time or just default to midnight if no time has been entered?
