Comment on Amazon Time Sync Serviceparent

Comments

To be clear, what I meant was "the fact that they're advertising whiz bang time synchronization, but then not using the correct protocol, makes me question the quality of the whole enterprise".

Even on local networks, NTP can only get you so close. If you set up chrony just so, in ideal conditions, I've gotten hundreds of microseconds (more commonly ~500-1000us). But combined with PTP, you can get sub-microsecond accuracy.

When Microsoft did that kind of thing we called it “embrace and extend.”

Microsoft already does offer PTP on Azure, and nobody calls it EEE.

That sounds different. Embrace and extend means implementing a protocol and then adding specific non-spec features. For example, postgres 'embraces' SQL and 'extends' it with specific features - in the future postgres could 'extinguish' SQL by breaking from the spec, forcing an ecosystem split.

Thank you. I was in the process of writing this exact comment but kept tripping over my own words and eventually gave up.
