Problems with WMS time support

[William Hudspeth]

Hello,

I am using Mapserver 4.10.1 on Red Hat Enterprise 3.

I am trying to display a GRASS raster image with WMS time support. I
have created a tileindex using gdaltindex, imported the tileindex
shapefile into PostGIS, and added a timestamp column containing the date
and hour in an acceptable format (e.g. 2007-04-16 01:00:00).

My mapfile entries for the tileindex, and raster layer are:

#*****LAYER - TILE INDEX FOR PM2.5 RASTERS (Time sensitive) 

LAYER
  STATUS ON
  NAME "pm25_time_index"
  TYPE POLYGON
  DATA "the_geom from pm25_dream_raster_view"

My WMS request looks like this:

http://phairs-devel.unm.edu:8080/cgi-bin/mapserv?map=mapmodule_wms.map&VERSION=1.1.1&REQUEST=GetMap&BBox=-120.000,26.000,-97.000,44.000&SRS=EPSG:4326&Width=459&Height=360&Layers=dream_pm25&TIME=2007-04-06T08


And, the error I get is below:

<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM
"http://schemas.opengeospatial.net/wms/1.1.1/exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1">

</ServiceException>
</ServiceExceptionReport>

Note how the raster referenced in the error is different from that
referenced in the WMS request. I can find no reference to the raster
referenced in the error output anywhere in my mapfile.

I would appreciate any insight into this problem.

Thanks, Bill
