i have rb2011 and i want to set date and time .i put alot of number in system >ntp clint like (64.4.10.33 - 65.55.56.206 ) but it set the date to jan/01/2002
the router os was 5.26 when i found this problem i upgrade it to 6.15 but the problem still there.
what is the solution?

is it sntp client you are using, what happens if you set NTP server to some other address?

i use ntp client
what did u mean with if you set NTP server to some other address?

for ntp/sntp default is empty or no address (0.0.0.0) in this case SNTP if enabled will switch to broadcast mode. While NTP client will not as you have to select what modes you want to be supported.

So if you change to the actual address SNTP will switch to unicast mode. Same, when you receive NTP servers from some dynamic configuration, like DHCP.

now what can i do to set the date and time? please
