Decode _gaexp cookie

Greetings to the community!

 

I was wondering if anyone can explain me the meaning of _gaexp cookie. Here's my example.

 

_gaexp=GAX1.2.TF9tJ2wxRoqwbGhlR489Hg.17297.0!dJ2pAmbVS9mTzgjNvgEtdg.17297.1

 

As a matter of fact, I understand everything in the string exсept the meaning of the number '17297'. Since the number is the same for both active experiments, I assume it has something to do with my Optimize ID or something like that. Can anyone shed light on this?

All the best,
Dmitri

That number is the expiration date for the experiment expressed in terms of days since the Unix epoch (Jan 1, 1970). It's purpose is to remove the cookie value for expired experiments.
