[mapserver-users] Guidance on using time dependent non-EPSG layers

I'm putting together a mapserver to serve satellite instrument raster
images that are on a projection that has no EPSG code. There is one
image per "time step" (when the satellite instrument observed it) and
the instrument is still recording data so new images will be added over
time. The software generating the images is producing tiled geotiffs.
I'm fairly familiar with geotiffs but not shapefiles or with the details
of mapserver. From what I've read I understand that serving data in a
non-EPSG projection is not strictly something the WMS-spec allows for,
but as long as I get images out I'd be OK with that.
I'm hoping someone can help me or point me to some more information
1. What are my options for adding a time dimension to geotiffs? If I
converted them to TileDB arrays with a time dimension would that work (I
plan on trying this out later today). I've gone through this basic
tutorial from TileDB but haven't tried adding a time dimension yet:
2. Is there a good way to serve non-EPSG layers? If the best way to do
it involves making up an EPSG code in PROJ, do I need to update the
Thanks for any guidance.
