Petascope_Translation to grid indices is wrong when coverage imported in descending order

[Bang Pham Huu]

for c in (test_import_order_descending_irregular_time_netcdf) return encode(c[ansi("2003-01-17T00:00:00.000Z")], "application/gml+xml")

as c is imported in descending order (import from coverage's origin to bottom) and the sdom© on time axis is [-6:0].

However, generated grid index for time axis is 6 outside of [-6:0].

SELECT encode(c[6,0:17999,-3600:719], "json" ) FROM test_import_order_descending_irregular_time_netcdf AS c
