How to update time with sntp using ntp.conf file

After the recent daylight saving time change, my macOS (Sonoma v14.1.1) clock no longer shows correct date and time. When I enable "Set date and time automatically" it reverts to January 22, 2023 and a wrong time. Therefore, I would like to manually synchronise my computer's clock with a time server. I would like to use Oxford's University time servers. I use sntp command.

sudo sntp -sS ntp1.ox.ac.uk

The command produces five sets of the following output:

sntp: Exchange failed: Timeout
sntp_exchange {
        result: 6 (Timeout)
        header: 00 (li:0 vn:0 mode:0)
       stratum: 00 (0)
          poll: 00 (1)
     precision: 00 (1.000000e+00)
         delay: 0000.0000 (0.000000000)
    dispersion: 0000.0000 (0.000000000)
           ref: 00000000 ("    ")
         t_ref: 00000000.00000000 (0.000000000)
            t1: E8F7357E.A265F0F5 (3908515198.634367999)
            t2: 00000000.00000000 (0.000000000)
            t3: 00000000.00000000 (0.000000000)
            t4: 00000000.00000000 (0.000000000)
        offset: FFFFFFFF8B846540.AECD078580000000 (-1954257599.317183971)
         delay: FFFFFFFF1708CA81.5D9A0F0B00000000 (-3908515198.634367943)
          mean: 0000000000000000.0000000000000000 (0.000000000)
         error: 0000000000000000.0000000000000000 (0.000000000)
          addr: 129.67.1.164
}

and exits with the following error message:

sntp: Clock select failed

My NTP server configuration is located in /private/etc/ntp.conf:

server  ntp0.ox.ac.uk
server  ntp1.ox.ac.uk
server  ntp2.ox.ac.uk
server  ntp3.ox.ac.uk

My questions are: 1) How do I make sure that the sntp command uses the nth.conf file above? At the moment I have to supply the NTP server address manually to the sntp command. 2) What do I need to change for the sntp command to succeed and set the time?
