Re: Problems with GRIB feature collections



Hi Roy,

This might take a bit. If we look at the time range on the "Best"
collection, we get:

Start: 2013-02-21T00:00:00Z
End: 2017-12-09T06:00:00Z

However, if we look at the time range on the "latest" (201712), we get:

Start: 2017-12-01T00:00:00Z
End: 2017-12-04T18:00:00Z

It's not clear where anything after 2017-12-04T18:00:00Z is coming
from, but I think I have a way of tracking it down if it isn't a bug
(again, it will just take a bit of time).

Cheers,

Sean
