Is it possible to change the address of the time server?

Please add the ability to change the address for the NTP server. The default one is not always available.

No. But why? no problem with the default one here since 3 years now.
Some ponctual ntp fails on logs but no more than 1 per day.

The fact is that I assembled an add-on for a 20x4 display and as additional information I display the current time on it.

I poll the time with the sys.date command twice a minute. But quite often the request returns an error.
There are two options to fix this. 1 - add a clock module to the arduino. 2 - change the address of the NTP server to the local one.

The second option is preferable.
It is a pity if this is impossible to implement.

Third solution, ask the ntp time every 30 Mn like in https://github.com/karawin/karadio-addons/blob/master/karadioU8glib/karadioU8glib.ino and calculate the right hour with interrupts.
