update_modified
I was getting miffed about calibre setting 'Modified Date' on a book whenever it unexpectedly changed something in the metadata for a group of unrelated books. I suspect that it was due to tag changes or something similar that had a global impact.

To resolve this issue I create update_modified, an offline tool that will, by default, reset the 'Modified Date' for a book to the youngest ebook file in that book's filesystem directory. It will not use the date of the opf file unless you request that the opf file date be used.
  • The tool is written in .net 9 since that is what I've been using at work.
  • It is offline since it uses 'calibredb' for all the database work. Seemed more future proof than direct sqlite.

The source and binaries are available at https://github.com/elamide/update_modified. Usage is described on the github readme.

Did you take a look at the Job Spy plugin? It has quite a few options for working with the Last-Modified field from within calibre itself.

I came up through the UNIX ecosystem. Job Spy looks to be an amazing multi-tool but I only needed something to manage the 'Last Modified' column. Job Spy is overkill for what I need.

The Last Modified plugin does not manage the 'Last Modified' date. It allows you to use a custom field as a last modified date. I did try the plugin but in the end it did not do what I wanted which was to manage the 'Last Modified' column supplied by Calibre. It was the impetus for making the tool 'offline' since it is not possible to manage the 'Last Modified' column from within Calibre due to Calibre being able to modify the column value at unpredictable times.

If one acknowledges that the calibre database schema adheres to strict 3NF rules then the updates to the Modified/last modified column are predictable… IMO.

I maintain a book level timestamped log of actions in OneNote with a onenote:// URL in the book's Links/#links custom column.

Think of Job Spy as BusyBox; a single executable with multiple entry points depending on how you invoke it
