Time of photo taken

I had several observations from one day (June 26th, 2019) synced with metadata of the photos and the correct date was used, but the same time (11:35 AM) was used for all the photos that were taken from 11:35 AM to 4:30 PM. Why would this be?

These?

When you uploaded them, did you do any batch editing in the uploader?

Yes there are them. I first did a batch upload to iNaturalist, then changed my mind and did one observation at a time from my windows explorer.
