I'd prefer a different property name. `user_expires` kinda suggests it
to be a boolean variable (e.g. whether the user expires at *some point*)
How about `account-expiry-date`? Also note that prefer to use hyphens
(-) instead of underscores (_) for new properties.

I'd maybe elaborate a bit: "Account expiration date as a UNIX timestamp"
or something like that.

Typo in `user_expieres`
Nit: maybe call it $expires/$expiry instead of $exp. Not much longer
but easier to follow.

Nit: Same as above
