Time Zone is Wrong on So Many of My Observations

Just finally noticed, after how many years and how many thousand observations?, that I’ve been uploading some (many?) of them with the wrong time zone. What I don’t get is that I recently did a batch from Arizona and they all went through, apparently, with the correct zone. Now as I do more of them from the same location, same cameras, they’ve got the wrong zone. Why?

Having “Is this worth it?” thoughts as I wait for a batch edit of obs from another location to finish batch editing. :/

Edited to add: Batch editing is working much faster than earlier so I’m cleaning up whatever I can find. Still timing out so I have to do each batch twice, though. Just assuming I’ll have to upload and then batch edit any future obs from different time zones as I don’t see an easier way to do it on the bulk uploader.
