NTP Client (Network Time Protocol) is the software client that allows your router to synchronize with an available time server. Your router's current time is listed in the upper right hand corner of the Web GUI when you log in to your router. Certain features such as "Access Restrictions" and the "Traffic by Month" graph will not function if the router hasn't synchronized with a time server. And if it has synchronized but the time has not been adjusted for your time zone, you may see unexpected behavior. You cannot set your time manually, and must do it via NTP. Don't be fooled by the time zone setting located at "Setup" > "Basic Setup" > "Time Settings". This setting alone is only to adjust the synchronized time from the server to match your local time.
As Brainslayer states "If NTP is disabled the time starts at zero which is 1 January 1970".
As mentioned, you cannot just manually set the time on your router and then forget about it. You can, however, set it to synchronize with a public time server using the NTP client and then forget about it. To configure the NTP client, log into the router and go to "Setup" > "Basic Setup" > "Time Settings". Now:
1) Select "Enable" next to NTP Client
2) Choose the appropriate Time Zone for your area
3) Set Summer Time (DST) as appropriate (See Time Zone settings below)
4) Enter the domain name or IP address of the time server you have selected (See Time Servers below)
Don't forget to Save and Apply settings.
How often does NTP synchronize? According to redhawk0, it is "checked at boot up...then after 120 seconds for a second time....that's it."

Have the clocks just changed in your area but you find that DD-WRT is still an hour behind/ahead? Open a Telnet/SSH command prompt and run these three commands:
ntpclient pool.ntp.org
stopservice process_monitor
startservice process_monitorCourtesy: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=271968#271968
DD-WRT will let you boost your router’s range, add features, and more.
DD-WRT has a ton of features—more than we can cover in this guide, which is focused on helping you get your router upgraded. Stay tuned, as we’ll go into more depth in a couple more days on all the great things you can do with it, but even if you don’t use the additional features, DD-WRT is worth installing to make your router work better.
Here’s our router. Behold: the Netgear WNR2000, revision 2.
Use GlassWire to Monitor Your Bandwidth
is a great firewall application for Windows that does a lot more than just block incoming connections. It’s also really amazing for monitoring your bandwidth usage.
The default view when you launch it shows you a graph of all network activity in real-time, which is pretty great, but once you switch over to the Usage tab you’ll see the real power of this application.
You can see your bandwidth usage by connection, whether it’s incoming or outgoing, and even drill down into individual apps to figure out exactly what is taking up so much bandwidth.
Just installed on Archer C7 V2(US). Had a lot of problems installing DD-WRT and thought I would show what worked for me.
I had been running it with the TPLINK stock firmware for a couple years and had updated to the latest factory firmware. When trying to install the factory-to-ddwrt.bin file I kept getting the 18005 error. Looking it up it seems this is because the later factory firmware tries to lock out unapproved updates. I tried to downgrade to several older versions of factory firmware and got the same 18005 error.
I read through this thread https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=287073 and several posts detailed very complicated procedures that seemed more trouble than I wanted to try. One post by "eginnc" sounded simple so I tried it.
He started with factory firmware 160719 so I went to TPLINK, downloaded that version, and it installed ok on my router. I then went to http://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2017/04-24-2017-r31899/tplink_archer-c7-v2/ and downloaded factory-to-ddwrt-US.bin since that was the file he used. I powered on the router with the WPS/reset switch pressed and held it for 30 sec. Then was able to connect to factory configuration pages and do a firmware update using the r31899 factory-to-ddwrt_us.bin and it worked. I then was able to update to DD-WRT build 41892 from the DD-WRT config pages and it is working fine for me.
