Fails to anonymize object with Issue Date of Imaging Service Request

… because we look for "Date" at the beginning or end of the element name:

UnboundLocalError: With tag (200b, 102b) got exception: local variable 'time_name' referenced before assignment

Scary, but probably best to just replace any "Date" with "Time" when looking for the element that encodes the time.
