Thank you for making me look harder at every aspect of the time stamp. I have multiple copies of photos taken with the multiple cameras with the correct time but and some are in the correct sequence and some are not. I finally noticed that some have an eastern time zone stamp and some a central time zone. All of the photos were taken in an eastern time zone location, but some I exported from Photos from a computer in the central time zone and I now have them ALL in one Photos library and they are not in the same sequence/order. Now that I am aware to check the time zone, I can correct the time for the appropriate time zone and they are falling back into sequence. Again, thank you...
