Hi,

Is there any way to get the time positions of a layer advertised in WCS 2.0.1 
DescribeCoverage? They are listed with WCS 1.0.0 but as can be checked with the 
demo service:
WCS 1.0.0 with time positions 
https://demo.mapserver.org/cgi-bin/wcs?SERVICE=wcs&VERSION=1.0.0&REQUEST=DescribeCoverage&COVERAGE=modis
WCS 2.0.1 that is unaware of times
https://demo.mapserver.org/cgi-bin/wcs?SERVICE=wcs&VERSION=2.0.1&REQUEST=DescribeCoverage&COVERAGEID=modis

Another service 
https://beta-karttakuva.maanmittauslaitos.fi/wcs/service/ows?service=WCS&version=2.0.1&request=DescribeCoverage&coverageID=ortokuva__ortokuva
puts timePositions into WCS 2.0.1 like this
<gmlcov:metadata>
<gmlcov:Extension>
<wcsgs:TimeDomain default="2021-12-31T00:00:00.000Z">
<gml:TimeInstant gml:id="ortokuva__ortokuva_td_0">
<gml:timePosition>1985-12-31T00:00:00.000Z</gml:timePosition>
</gml:TimeInstant>

I have already learned that Mapserver cannot handle time as a dimension like 
Geoserver does 
https://lists.osgeo.org/pipermail/mapserver-users/2019-January/080917.html but 
it would be nice at least to have some way to show the users which time periods 
are available.

Another little issue with Mapserver WCS 2.0.1 is that it shows the coordinate 
axis labels of EPSG:3067 this way
<gml:Envelope srsName=http://www.opengis.net/def/crs/EPSG/0/3067 axisLabels="x 
y" uomLabels="m m" srsDimension="2">

Obviously there is no way to change axisLabels into "E N" but I hope I am wrong.
