Hello there,

I get the following error message. It looks like it is failing on the TIMESTAMP:

> python3 jwt_tool.py [JWT_TOKEN]

=====================
Decoded Token Values:

The value of the iat is 07/07/2020 12:35:40 . jwt_tool is expecting a timestamp and that's why is failing.

Yes, looks like the token you're testing is having fun with the RFCs. Fairly uncommon issue, but I might something to handle errors like this gracefully in v2.0
