Timestamp zone in photos file name in iOS is following the UTC while expected to be in EST.

I have the same problem as mentioned in this post:

Any idea if someone figured out how to solve this problem?

The file name of phosts uploaded to OneDrive is something like yyyymmdd_hhmm000_iOS.png. I think the last 3 digts is a seq number to avoid having duplicate file names. This is fine for me but how I can make sure it is in EST timezone not in UTC?
