Hi,
I found the solution to this problem.
When using shp2pgsql the data type for the date and time column are set to varchar datatype.
Make sure that the table was create with DATE datatype for timestamps columns.
Example:
CREATE TABLE "mapserver" (gid serial PRIMARY KEY, "location" varchar, "time" date, "imgdate" date);
The WMS time filter works fine now with PostGIS connection.
