No, it is not for getting time stamps. For that, you read the PHC
device directly, and then convert using values from the UDS message.

Perhaps a more realistic use case is to produce a pulse train from the
PHC into some other device. The values from the UDS message help you
program the other device to properly interpret the signal.

Thanks,
