nbf check is incorrectly implemented

[mediamonks-arjan]

I'm getting this error:

1451384603 '>=' 1451384603
NotBeforeError: jwt not active

From this line:

node-jsonwebtoken/index.js

Line 213 in f1fb176

console.log(payload.nbf, '>=', Math.floor(Date.now() / 1000));

The spec states:
https://tools.ietf.org/html/rfc7519#section-4.1.5

The processing of the "nbf"
claim requires that the current date/time MUST be after or equal to
the not-before date/time listed in the "nbf" claim

In the example above, the current date/time is equal to the not-before date/time, so it shouldn't give an error.
I think the >= should be changed to >, because when equal the nbf should be valid.

Thanks, fixed in v5.5.1
