iOS Photos app displays incorrect time for imported pictures

I have photos, that I make with my camera in travel, imported to iCloud. All the pictures have a timestamp in EXIF properties in local time of the place I took them (GMT+2). Also, they have GPS coordinates set. I live in GMT+5 time zone.

But Photos app on my iPhone shows a wrong time to all imported pictures (-3 hours) and correct time for pictures, taken on iPhone. Because of that, all the pictures are mixed.

How can I fix that? Probably, I need to set some other EXIF attribute for them?
