[time-nuts] Re: Time stamping of data

[Ed Marciniak]

If you’re referring to IEEE-1588 precision time protocol, there are many references to it.

In a nutshell with appropriate hardware clocks, a capable network interface can pass the exact time it sent or received a given packet. This allows for removal of operating system processing delays and jitter. In general, sub-microsecond accuracy is possible with suitable hardware.

Suitable network gear might even include a GPS receiver to get time, and a pulse per second input from the same, as well as possibly external 10MHz and pulse per second inputs. An example use case would be timestamping things like financial transactions.

Subject: [time-nuts] Time stamping of data

Hello,

I keep reading references to time stamping, but
am only vaguely aware of what this does and how
it is done.

Is there a sort of "primer" on the subject?

Thanks,

Dana Whitlow
