How to set expiration with examples. about jsonwebtoken

[Figments]

I can't seem to figure this one out. You say "Now + an hour", but what does that even mean? Are you using std::time::SystemTime::now() and somehow casting that as a usize value? I can't seem to do that.

The exp field should be a UTC timestamp, so now + 1h would mean current UTC timestamp + 3600

[Figments]

So then the type of the exp field should be from the std::time library or chrono? Or does it matter?

I ask because all your examples have the exp field set as some arbitrary usize value, but that doesn't seem to work whatsoever.

[Keats]

How you get the timestamp doesn't matter, at the end it should be just a UTC timestamp, so a usize effectively. In the tests, we do https://github.com/Keats/jsonwebtoken/blob/master/tests/lib.rs#L39 for example.
