WMS time - filter do not works

[rmarzocchi84]

Following [1] I try to set a WMS time layer raster. The example works but if I use a wms_timedefault different from the filter time it do not works.

In the following example I see always the raster of 2018-08-17

METADATA
       "wms_title" "bui_20180101"
       "wms_srs"   "EPSG:3003"	
       "wms_extent" "1436301.37500 4916704.50000 1701801.37500 5177704.50000"
       "wms_timeextent" "2017-08-01/2100-12-31/PT5M"
       "wms_timeitem" "day" #datetime is a column in postgis table of type timestamp
       "wms_timedefault" "2018-08-17 00:00:00"
       "wms_enable_request" "*"
       #"ows_include_items"     "all"
     END
     OFFSITE 0 0 0
     TILEITEM "location" #filepath is a column in postgis table with varchar of the filepath to each image
     TILEINDEX "time_idx"
     FILTER (`[day]` = `2018-01-01 00:00:00`)

I also checked all the options / suggestion of the [2] page
