Linux Mint Cinnamon 19.3 x64.
В закрытой локальной сети (без доступа в интернет) находится сервер с Windows Server 2003, на котором включен сервер синхронизации времени w32tm. В этой же сети находятся ПК с linux Mint 19.3, на которых настроена синхронизации времени с этим сервером. Синхронизация в локальной сети не работает, но если подключить ПК к интернету - время синхронизируется.
Никаких препятствий в виде роутеров в защищенной сети нет. ПК с Виндой, находящиеся в этой сети успешно синхронизируются.
Пробовал синхронизацию с помощью timedatectl и ntp, прописав в конфигурационные файлы айпи сервера (т.е. 192.168.3.1, он же kmis-3). Он появляется в списке серверов времени, отображается разница во времени между компьютерами, но синхронизация времени не работает. ЕСЛИ выполнить команду ntpdate 192.168.3.1 - то время синхронизируется.
Удалил ntp, выключил timedatectl, установил chronyc. Не синхронизирует :(

# Welcome to the chrony configuration file. See chrony.conf(5) for more
# information about usuable directives.
# This will use (up to):
# - 4 sources from ntp.ubuntu.com which some are ipv6 enabled
# - 2 sources from 2.ubuntu.pool.ntp.org which is ipv6 enabled as well
# - 1 source from [01].ubuntu.pool.ntp.org each (ipv4 only atm)
# This means by default, up to 6 dual-stack and up to 2 additional IPv4-only
# sources will be used.
# At the same time it retains some protection against one of the entries being
# down (compare to just using one of the lines). See (LP: #1754358) for the
# discussion.

Warning: The system is configured to read the RTC time in the local time zone.
This mode can not be fully supported. It will create various problems
with time zone changes and daylight saving time adjustments. The RTC
time is never updated, it relies on external facilities to maintain it.
If at all possible, use RTC in UTC by calling
'timedatectl set-local-rtc 0'.
