Wrong photo upload time

-
Hello,

Instagram is recording the wrong photo upload time on my photos. I am a business and am worried this is affecting the algorithm?

If I post at 11 AM it records as posting at 3 AM, 8 hours behind. I am in the UK, so I am GMT zone. Wondering if Instagram thinks I'm in a different time zone.

I noticed this because my 'reach' went down dramatically a few days ago.

Any help?
