Please send your replies via the list so that others who know better
than me about time support can help, and that other users who may have
similar problems can benefit from the answers when they search the archives.
Back to your last question, at first sight, what you have seems right,
and already combines the spatial index and time index. If you have
multiple images listed in your OMTO3ECOLUMNAMOUNTO3IDX layer that fit in
the requested map view and whose time attribute match the requested
time, then they should all be displayed.
If that doesn't work for you, then you will have to provide more
specific details to help us understand the exact problem.

Daniel,
I also use postgis to generate time index, just like this:
LAYER
STATUS ON
NAME "OMTO3ECOLUMNAMOUNTO3IDX"
TYPE POLYGON
CONNECTIONTYPE POSTGIS
CONNECTION "dbname=mapserver password=anonymous user=anonymous
port=5432"
DATA "the_geom from omto3e_003_columnamounto3"
METADATA
"wms_title" "OMTO3e Total Ozone Solution Index"
"ows_service" "none"
END
END
LAYER
NAME 'OMTO3e_ColumnAmountO3'
TYPE RASTER
STATUS ON
PROCESSING "SCALE=50,700"
DEBUG ON
DUMP TRUE
PROJECTION
"init=epsg:4326" ##recommended
END
METADATA
wms_title "Best Total Ozone Solution" ##required
wms_timeextent "2004-08-30/2010-04-03"
wms_srs "EPSG:4326"
wms_timeitem "time"
wms_timedefault "2010-04-03"
wms_extent "-180.0 -90.0 180.0 90.0"
END
TILEITEM "location"
TILEINDEX "OMTO3ECOLUMNAMOUNTO3IDX"
END
The TILEITEM "location" in database points to a data file. Do you
mean "location" can point to an individual tiled image and MapServer can
tile up couple of tiled images which have the same timestamp?
Thanks.
