hmmm… i don’t currently see an issue with this particular observation:
i tried to recreate the problem, but i couldn’t.
the only bugs i noticed were similar to those mentioned in Mismatch in Time representations between English and Korean - Bug Reports - iNaturalist Community Forum.
however, the first issue that i noted in that other thread (related to AM/PM switching) manifests differently when using the uploader in Russian. in Russian, i see a утра button in the time selector, and when i click it i see the output datetime change to вечера, but the button itself remains as утра rather than toggling. so you can’t toggle the output datetime back to утра using the button.
