That depends on what you mean with wrong time - are you seeing 12-hour format or 24-hour format and which one are you expecting?
Or is the clock outright wrong e.g. 10:34 when it should be 12:34?
Does your /etc/localtime symlink to the correct timezone?
$ ls -l /etc/localtime
lrwxrwxrwx 1 root root 37 12 mar 13:23 /etc/localtime -> /usr/share/zoneinfo/Europe/Copenhagen
Did you enable the ntp client
systemctl enable --now systemd-timesyncd
