I have been using archivebot.py to archive discussion pages on Armenian Wikipedia for a few years. A few days ago I noticed that it archives threads that should not be archived (example, last reply in the "Ադմինիստրատորների պասիվություն" thread is 2 days old, but the settings on this page is 30 days).

I think the reason is that the time for the last signature is 20:15, 20 հունվարի 2024 (UTC) (հունվարի means January in Armenian but it is using lowercase հ, instead of uppercase Հ). When I look into old discussions, the uppercase version was used before and I have no idea why this changed. Anyway, I tried to modify the script and this version works fine (example). Basically, in the constructor of pywikibot.textlib.TimeStripper I change it to add both uppercase and lowercase versions for Armenian (similar to Vietnamese) month names to origNames2monthNum.
