Hi all,
My MapServer WMS service seems to be misusing the default times I have
defined on map layers. It (correctly) uses the default time for GetMap
requests that specify no time at all; however it (incorrectly) uses this
time also for requests that specify a time outside the layer's available
times. (For, say, time=2017-09-21, it returns today's image... which is
very confusing.)
The WMS Capabilities doc shows <Extent name="time" ... nearestValue="0">
which is what I want -- but it doesn't match the above behavior. Excerpt:
<Layer queryable="0" opaque="0" cascaded="0">
<Name>iicmocp_time_idx</Name>
<Title>Time Index for iicmocp</Title>
<SRS>EPSG:4326</SRS>
</Layer>
<Layer queryable="0" opaque="0" cascaded="0">
<Name>iicmocp_daily</Name>
<Title>csppnppviirssdr iicmocp daily</Title>
<Abstract>Some important description here...</Abstract>
<SRS>EPSG:4326</SRS>
<Dimension name="time" units="ISO8601"/>
<Extent name="time" default="2013-06-11"
nearestValue="0">2013-06-09/2013-06-11T09:16/P1D</Extent>
</Layer>
Is this a bug in mapserv? Or have I just misconfigured my time index?
(Mapfile excerpts below.)
Thanks.
