User's locale affecting AM/PM of some observations

[tiwane]

From https://forum.inaturalist.org/t/incorrectly-shown-time/31450

1. With your account's locale set to English, upload this photo via the web and give a location of 55.901087, 37.849474 (in the Moscow area).
2. The observation should show the correct observed on time, according to the photo's metadata.

3. Its JSON shows an observed_on_time of `2022/05/01 11:04 PM` 4. Change your account's locale to Russian. 5. Upload the same photo and give it the same location. 6. Observation shows AM (both in Russian and English, here's the English screenshot)

7. Its JSON shows an observed_on_string of `2022/05/01 11:04 вечера`

Weirdly, though, if you upload this photo and use 55.902732, 37.848835 for its location it works fine in both English and Russian account locale settings.

Some questions

1. When you say "The observation should show the correct observed on time" do you mean on the obs detail page, e.g. https://www.inaturalist.org/observations/115012325?
2. When you say, "its JSON" do you mean https://www.inaturalist.org/observations/115012325.json, https://api.inaturalist.org/v1/observations/115012325, or something else?
3. There is no JSON attribute called observed_on_time that I can see, but maybe I'm not using the right parameters. What URL are you looking at when you see that?
