We are attempting to use the WMS TIME parameter with a temporal view on
Oracle 12c. The view is based on a join of several tables, one of which
has geometry, and another of which has a valid time period defined using
the columns VALID_START and VALID_END. According to Oracle 12c practice,
rows which are do not have a set end time have VALID_END = NULL.
When we set the Time dimension columns on the Layer, when a WMS request
with no TIME parameter is made, we see an error:

Is this expected behaviour? Is the TIME parameter required on all requests?
