RB750Gs don't have batteries that keep the clock going like computers do. Implement NTP.

Google "public ntp servers" or "ntp pool" to get servers you can use.

No.

Well. I'm not 100% sure on that, but I doubt it. RB1000s don't have batteries, either.

Ok.

So i went to system ntp servers

and i added primary and secondary servers.

But how do i tell it to update the system clock?

cause it said conencted. but the clock is still on old time.

[admin@RB750] > /system ntp client print
             enabled: yes
                mode: unicast
         primary-ntp: 196.35.241.17
       secondary-ntp: 196.4.160.4
       poll-interval: 4m16s
       active-server: 196.4.160.4
    last-update-from: 196.4.160.4
  last-update-before: 57s940ms
     last-adjustment: 2h1s608ms579us

@Zapnologica

Did you set your TimeZone properly?
Set logging rules for 'ntp,debug,packet' an observe what's wrong.
System clock should be updated automatically.
Do not change mode to 'broadcast', keep 'unicast'.
I use these reliable time servers:
primary-ntp: 150.254.183.15
secondary-ntp: 150.254.183.8

my bad, it seems that broadcast only accepts messages from ntp server, while unicast sends request to check time. No matter which mode u use it should work.

Hi,

RB is NTP client, use 'broadcast' mode in case in your network is time server which periodically broadcast time messages. In 'unicast' mode RB sends request to time server and receive message.

Hi there,


There is somethign that i have noticed on 4 of my RouterBoards.


I have set them all up as NTP clients and if i go to system/clock it shows the right time.


But if i go look at web proxy cache the times are wrong there?


Why would this be? i find it very odd. and each RB is off by a different time, the one is 2 hours behind, the one is 4 days behind.


I jsut find it very strange.
