Hello and welcome. My name is Keith Barker.
And if someone came up to us and said, "Hey, what time is it?"
And then they asked another person, "What time is it?"
And those times were different. You know, that's okay.
Maybe one person has an analog watch or something,
maybe it's off by a few minutes or a few seconds.
But in a network, it's important to have accurate time
on our devices for a lot of reasons,
including synchronization of logging information
for multiple devices and validation of digital certificates.
Or if we have systems that are doing financial transactions,
we need to make sure that they have the accurate timestamps WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
we need to make sure that they have the accurate timestamps
on each of those transactions.
And timestamps are also important for databases
that may exist across multiple systems
to make sure we have the accurate information
documented at the right time.
And the great news is there's more than just one way
of synchronizing time across our networks.
And we'll take a look at a couple options in this set of videos.
So if you're ready, I'm ready.
And I'll see you in the next video
for the overview of time synchronization protocols.
