Example: `userdate:PT1H` to select only articles modified by user during the last hour Fix https://github.com/FreshRSS/FreshRSS/issues/4280#issuecomment-3393078024 Useful for instance to bulk mark as unread recently marked articles by error: 1. Click on the toggle button to show the read articles (making sure the toggle for the unread articles is off) 2. Sort by *User modified 9→1* 3. Filter by *user modified date*, for instance to the last 3 hours by typing `userdate:PT3H` 4. Click in the drop-down menu *Mark selection as unread* P.S.: I have added at the same time a bunch of unit tests for date-related logic
