JSON Web Token Expiration
API Manager uses the Coordinated Universal Time (UTC) time zone for the JWT token expiration and uses the current time on your computer as the baseline time for the token expiration. The token expires on the expiration date you configure and a minute earlier than the time at which you generated the token.
For example, if you generate the token on January 10 at 2:30 p.m. and set the expiration date as January 11, the token expires on January 11 at 2:29 p.m. If you set the expiration date as January 15, the token expires on January 15 at 2:29 p.m.
After a token expires, you cannot refresh it. You must generate a new token.
