Describe the feature or enhancement you're looking for
Currently the date that a mosaic was generated is not stored anywhere (besides in the file attributes of the COG itself). This information is very important because a mosaic will be out-of-date if corrective work has been performed on individual layers and it hasn't yet been regenerated.
Describe alternatives you've considered
The date could be baked into the mosaic file name as well. The only downside with that idea is that if a mosaic is regenerated twice in the same day, and TiTiler has looked at the first file, it will error on the regenerated new file (which would have the same name) until it has been restarted.
Additional context
There is more metadata creation and such that should accompany the mosaics during download, so this is just the first of a few related items that should be done.
