As discussed, the dates are listed based on actual uploads like recent changes,
selecting a single date will show models updated on the exact date like recent changes,
a range selection (can be on either side for convenience) will show all updates between the dates, inclusive,
and base filtering date selection is fully supported as with previous updates.
---
There is a small difference from recent changes - the date used currently when no bases are filtered is the global update date (latest of all models),
does NOT check every base's change date. If a single base is selected, that base's date will be the one used.
This is because of the range behaviour - we probably do not want multiple entries when the model has been updated multiple times.
In a potential phase 2, bases would be displayed directly and then multiple entries split across dates are a possibility.
