Simone,
Thanks for responding and no problem - I created a JIRA issue:
https://osgeo-org.atlassian.net/browse/GEOS-8901
The issue also references this thread in case someone does respond with a
solution.

Dear Marc,
can you please file a JIRA report for this.
Apparently nobody has time or will to help but I believe it is worth taking
note of this.
Regards,
Simone Giannecchini

Hi,
Has anyone been able to get a WFS GetFeature fes:Filter with the Temporal
operators to work with an operand of TimePeriod?
The Goeserver GetCapabilities states that the two operand options are
gml:TimeInstant and gml:TimePeriod, but I can only get TimeInstant to work.
Example of gml:TimePeriod that doesn't work ( I also tried different operators
and one level up on the xpath ValueReference, but it seems the issue is
Geoserver parsing the TimePeriod itself)

For reference, here is the query portion of a request using gml:TimeInstant
that works:
<Query typeNames="private:FeatureName" handle="Query">
<fes:Filter>
<fes:TEquals>
<fes:ValueReference>private:FeatureName/om:OM_Observation/om:phenomenonTime/gml:TimePeriod/gml:beginPosition</fes:ValueReference>
<gml:TimeInstant
gml:id="id2"><gml:timePosition>2018-08-14T16:00:00Z</gml:timePosition></gml:TimeInstant>
</fes:TEquals>
</fes:Filter>
</Query>
I tried checking for examples in the unit tests, but from what I found it looks
like they neither use a TimeInstant or a TimePeriod which doesn't really jive
with what the Geoserver GetCapabilities states. The examples also seem to only
show the equivalent of a TimeInstant filtering on a single time.
thanks in advance!
