time not syn from NTP server

[Libertis]

I have a T42S, with firmware 66.84.0.15

It does not update time it always sets 26.11.18

If I set it manually, after reboot, again it is 26.11.18

I have to say, that it is also impossible to register, although other Yealink devices do, to same provider using same configuration.

Thanks for advice

I have a problem with my phone Yealink SIP-T46G.
Firmware version 28.80.0.60
DHCP Time = Disabled
Primary Server = 0.ca.pool.ntp.org
Secondary Server = cn.pool.ntp.org

N.B.: i tried the two servers 0.ca.pool.ntp.org and cn.pool.ntp.org on multiple devices and works very well.

the problem is:
- The time synchronizes with the NTP server, but the wrong time is displayed.
Thank you to offer me an effective solution to this problem.

I followed the steps down, but still the same problem:
------------------------------------------------------
1.check if you have enable "DHCP time" feature,if yes,please disable that,then test again.
2.check if you select a correct time zone?
3.check if your NTP sever address is correct?

Thank you
