DNS_ERROR_RCODE_BADTIME
DNS_ERROR_RCODE_BADTIME means the signature validity time on the DNS request was unacceptable. Clock skew, a stale signed request, or a signing-window mismatch can cause it.
What to check
- Verify time synchronization on the DNS server and on the system submitting the signed request.
- Check whether the request was delayed or replayed beyond the configured signing tolerance.
- After correcting time and key state, generate a new request instead of replaying the failed message.
