Jackie and Jon, I've updated this patch and rewritten it (and the other power timeout one) to be multi-version. It will be released in v53 once GeoffR's patches are updated (if he doesn't show up in a few weeks, I'll figure those patches out), or you can copy-paste from GitHub or below:

Larger Sleep/Power-off timeouts:
  - Enabled: no
  - PatchGroup: Sleep/Power-off timeouts
  - Description: |
      Increase the available sleep/power-off timeouts to larger values (up to a
      few weeks). See https://www.mobileread.com/forums/showpost.php?p=3887105
      for additional values.
