Saw this got released in 0.112.0. We use OTP MFA, so clock sync is important to us. So just tried to use it with the example configuration here: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/ntpreceiver/README.md , but getting this error when validating the config and trying to restart the collector:
