Now, the router should know what time zone it’s in and adjust the clock offset appropriately.

Once you’ve done that, the system should update with a message telling you that the current time zone has been updated. Starting with the ISR, Cisco started keeping the time synced more closely when the router was shipped from the factory, and the battery keeping the hardware clock time when powered off seemed to last a lot longer.Īt this point, we need to set the router’s timezone with this command: R1(config)# clock timezone When you first connect to the router, you will either see the default time of 00:00 (for older routers), or if you’re on an ISR or newer router, it may be synced fairly close to the actual time. CST is six hours behind the GMT clock (GMT -6). In the case of my example, the central United States is in the Central Standard Time Zone (CST). The fact that I myself am in the Central Time Zone and therefore would not need to do any additional thinking to write my examples is purely coincidental. For the purposes of the examples in this post, I’m going to assume the router is located in the central United States and is in the Central Time Zone. That way, if you have devices spread all over the world, you never have to worry about a significant time difference because one clock was synced to local time and the other was synced to GMT with an offset applied. In today’s world, it is far easier to keep the clock of your device synced to GMT, then apply an offset to show you what the local time is. First, you need to know what timezone you are in and what your GMT offset is. So how do we get our network clocks to report the right time? Well, the process is fairly easy, provided you’ve done a little homework about a couple of things. If there is a security incursion into your network devices, you need to track the time the device was accessed in order to be able to accurately report the event to the proper authorities. When debugging a call hand-off on a voice gateway, an accurate router clock ensures that you can match the time the call was placed with the debug message output.

But as systems have increased in complexity over the past several years, the need to have all the time on your equipment accurate has become paramount.

And when the router would reboot, the software clock didn’t have an accurate hardware clock to refer to, so it used 00:00 as the reference point. In fact, most older Cisco routers didn’t even include an on-board battery to keep the clock accurate. What about network equipment? In days past, the routers and switches were typically neglected when it came to clock setting.

And if those clocks drift out of sync, heaven help the server admins.

Novell and Windows both utilize systems to ensure that the clocks of all the servers in the network are synchronized. Directory structures depend on an accurate clock to authorize logins and track audit events. Keeping accurate time in a computer environment is very important to systems. As soon as he showed me that one command, it all made sense. The lab router returned the now-familiar string of (he’d just booted it). When I asked how he could be so sure after such a short amount of time, he consoled to a router in his lab and typed in “show clock”. I was once told by a consultant that he could figure out whether a client needed his services after about 30 seconds at a router console.
