Offsets can change. Turkey switched from GMT+2 with DTS to GMT+3 without DTS a couple of years ago. If you were to store +2, you wouldn't be able to reconstruct the current date from it, while having Europe/Istanbul would give you either +2 or +3 depending on the revision.

So a better option is to store UTC + timezone + revision (i.e. timezone as it was in 2014 to figure out the offset later)

Indeed. So when the Turkey/France meeting moves, what then?

But I get you. You want the point in time to stay "the same" in the local "common sense" time, whereas I was thinking international cooperation in which case anchoring it in Turkey could hurt more than help.

Well that means that you've decided on an exact number of seconds from now, no matter how timezones change. So what's the point?

Why not just have UTC+offset, then? timezone+revision is exactly equal to offset.
