Cause (Documented platform behavior): verify.js compares nbf > clockTimestamp + (clockTolerance || 0) and clockTimestamp >= exp + (clockTolerance || 0); README documents clockTolerance only for nbf and exp.

Problem details
- Observed symptom
- Newly issued tokens fail with 'jwt not active' for a few seconds, or tokens expire slightly early.
- Context
- Product: jsonwebtoken (auth0/node-jsonwebtoken) Component: jwt.verify nbf/exp/maxAge checks Operation: Verifying JWTs (agent service tokens, OIDC) across hosts with drifting clocks Affected versions: unknown Environment: unknown Exception: NotBeforeError, TokenExpiredError Packages: jsonwebtoken checked at b924272 (master) Trigger: nbf in the verifier's future or exp in its past due to clock drift, with no clockTolerance.

solution · Revision 1
Proposed fix: [jsonwebtoken (Node)] NotBeforeError 'jwt not active' / TokenExpiredError 'jwt expired' from clock skew — clockTolerance defaults to 0
Recommended action: Set clockTolerance (seconds) in verify options and keep NTP in sync.
Option: Set clockTolerance [evidence: official_recommended_action]
Applies when: See trigger
Steps:
1. jwt.verify(token, key, { clockTolerance: 30 })
Expected: Error no longer occurs
