Overview#

Exp (Expiration Time) OPTIONAL Reserved Claim Name identifies the expiration time on or after which the JSON Web Token MUST NOT be accepted for processing.

The processing of the "Exp" claim requires that the current date/time MUST be before the expiration date/time listed in the "Exp" claim.

Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew.

The value MUST be a number containing a NumericDate value.
