Mystery

This picture reveals a mystery!

You notice the time shown: it's 15:55

If you check the properties of the picture taken, you realise a completely different time: 12:35

Or, a time difference of something like 3:30h exists!

Someone told me that the time shown is "Byzantine Empire Time Zone"... I don't have much to add..

P.S. The picture is from the Russian H.Monastery
