<p>Thanks for your answer, I'm indeed now testing my build in my command line. </p>
<p><br>
</p>
<p>But I'm still having the issue... </p>
<p><br>
</p>
<p>Query:</p>
<p>mapserv -nh "QUERY_STRING=map=/path/to/mapfile/climate-WCS-en.map&SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&COVERAGEID=DCS.TN.HISTO.YEAR.ABS_PCTL25&FORMAT=image/tiff&SUBSET=time(%221978%22)"
<br>
</p>
<p><br>
</p>
<p>I get the error: </p>
<p> <?xml version="1.0" encoding="UTF-8"?> <ows:ExceptionReport xmlns:ows="http://www.opengis.net/ows/2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<ows:Exception exceptionCode="InvalidSubsetting" locator="subset"><br>

</ows:Exception><br>
</ows:ExceptionReport><br>
</p>
<p><br>
</p>
<p>Any idea what might be causing this ?</p>
<p><br>
</p>
<p>I also tried adding the "ows_timeformat" "YYYY" at the WEB metadata level without success...
<br>
</p>
<p><br>
</p>
<p>Thanks</p>
