# `semantic.revocation_delay_invalid`

Revocation delay is not a positive duration.

Area 8, [Identity](../topics/identity.md); not declinable; the next step is usually the agent's.

```jadpo
application {
    revocation_delay: 0m
}
```

```text
error: `0m` can't be a revocation delay
 --> main.jadpo:2:23
  |
2 |     revocation_delay: 0m
  |                       ^^ not above zero
  reason: `revocation_delay:` is how long a disabled caller or a revoked session may keep working, a duration above zero such as `5m`; leaving it out checks the caller's record on every request.
  next: Write a duration such as `5m`, or leave `revocation_delay:` out (agent)
