Subject: [PATCH] Handle empty date-time gracefully

Some API's return an invalid, empty string as a date-time property.

DateTime::__construct() will return the current time for empty input
which is probably not what is meant.

The invalid empty string is probably to be interpreted as a missing
field/value.

Let's handle this graceful.
