Hi Michał, Looking at the code, I think this is an error in the documentation - time ranges in WCS 1.0 do not seem to be supported. There are no tests that cover time ranges either.
You could use runtime substitution to create your own queries with custom parameters e.g. START_DATE=2022-03-10&END_DATE=2022-04-10 The section at https://mapserver.org/ogc/wcs_server.html#spatio-temporal-indexes recommends using a TILEINDEX for the layer.
