Does Network Time Really Matter? | Network Fundamentals Part 22

Does it matter if our routers, switches, and other devices on the network have the correct time and date? Why, yes it does! Think of logging and troubleshooting, which makes use of timestamps. Think of security applications like Kerberos and certificates. And think of scheduling events. We can configure time manually on each router or switch. Unfortunately, this is time-consuming and often inaccurate. So, we have an alternative, called Network Time Protocol, or NTP. NTP servers provide the correct time to NTP clients on request. NTP servers are organized into layers called stratum. Each stratum of NTP servers acts as a client to synchronize their time and date with a server in the stratum above. We can configure clients to use a local NTP server in our network (perhaps a Domain Controller), or we can configure them to use a server on the internet (perhaps from pool.ntp.org). We can even select a preferred NTP server and have others configured as backups. Synchronizing can take a while on the first attempt (perhaps 10 minutes), so you will need to be patient!
