Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):

Step 1: Time representations in the normal view and in “Edit” view are mismatched.

Step 2: In the normal view, the observed date is “Sep 4, 2021 · 8:31 AM KST” but in the “Edit” view, “2021/09/04 8:31 오후 KST”. The Korean “오후” means PM but not AM. The actual time is PM.

Step 3: I guess the problem occurred from the different selection of the language when uploading new observations. I’ve always uploaded with the language “English” selected. But today, I changed the language into “Korean” for the ease of the inserting Korean names of the several species just before I uploaded my observations. There has been no such mismatch before.

in the upload screen, if you select a PM time (오후) from the date picker, you end up with an AM time (오전):

… and if you select an AM time, you end up with a PM time:

… but regardless, the observation gets an AM time because the system seems to ignore the Korean characters and just interprets the time as if 24-hour format. compare the observed_on_string and time_observed_at values for the 2 observations below:

it seems like selecting an AM time in the date picker and ending up with a PM time in the observation card is an English problem, too:

so then there’s a screen bug in the date picker, plus a separate bug that doesn’t interpret the Korean 오전 / 오후 and treats the time as 24-hour instead of 12-hour format.

UPDATE: interestingly, if i upload a photo and the time is added to the observation from the metadata, then the AM / PM is displayed and loaded just fine.

Thanks for the interpretation, @pisum!
