render temporal extent without time

[wiesehahn]

In most (I would guess 99%) catalogs listed at https://radiantearth.github.io/stac-browser/#/ the temporal collection extent is defined up to the day (e.g. start date is 2010-05-14T00:00:00Z), which is rendered by stac-browser as 2010-05-14T 00:00:00 UTC.

While it might be that 00:00:00 is actually the starting time I think in most cases this is just to fill the time slot.

I think it would look a lot cleaner to render the temporal extent simply as a date range (e.g. 2010-05-14 - 2020-06-14) if time is 00:00:00. Or as optional for all date ranges.

Would this make sense?

I guess that makes sense for collections as long as you get the full information on the collection page itself.

Note: This comes from the upstream stac-fields implementation and needs changes in STAC Browser and STAC Fields.
