The "modified" date is the date the metadata was modified. Adding or modifying a format does not change the metadata, so it does not change the date.

You can get the date that the formats are modified using the formats_modtimes template function. This list is sorted so that the latest change is the first item in the list (accidentally today, guaranteed with the next release). As such, a composite custom column (column made from other columns) containing the following template will show you the date and time of the most recently modified format.

Code:

{:'re(list_item(formats_modtimes('iso'), 0, ','), '^.*?:', '')'}

This template

gets the list of formats and their modification times formatted using the 'iso' date format that includes both the date and the time. (formats_modtimes)
selects the first (the most recently modified) format (list_item)
Strips off the format name (re)

Sorting the library by this column should give you what you are looking for.
