Another token expiry issue about jwt-cpp HOT 3 CLOSED

Resolved. I was over complicating time calculation, not a problem with your library.

 .set_issued_at(jwt::date(std::chrono::system_clock::now()))          
 .set_expires_at(jwt::date(std::chrono::system_clock::now()+ std::chrono::minutes{EXPIRY}))

is the right way, it seems (as long as validation and generation happens on the same system)

Quick side note (I already looked at it before you closed it).
The time you provide must be utc.
get_time uses the local timezone I believe while the library uses std::chrono::system_time::now() by default, which is utc. This results in the token being expired at the time of creation.
You can change the clock used by specifying a custom clock struct on the creation of the verifier, however, I strongly recommend against it, as the standard specifies utc and that would break compatibility with every other system.

Thanks - I'm curious if it would be possible to post an example of the right way to get UTC time somewhere in your documents? I know its not related to your library, but I think it is a common requirement along with this application and an example that shows us how to correctly pick UTC everywhere will be very useful. Thank you.
