Background:
This general problem was noted as long ago as early 2019 on kali forum
Basically suggests: uninstalling ntp should solve this problem.
systemd-timesyncd.service conflicts with ntp
In depth breakdown of kali issue with auto adjust time/date
Good overview of date/time auto adjust and ntp
how to manually set and sync ntp and system time
Wish project helped and prevented these guys from having to reinstall os to get date/time working
Solution : uninstalling ntp should solve this problem.
systemd-timesyncd.service conflicts with ntp
sudo apt-get remove ntp
systemd-timesyncd will be auto installed upon ntp removal timesyncd will allow auto-adjust of date/time sufficient for authentication entropy
timesyncd : in Debian), there exist a service integrated in systemd for processing the time synchronization
systemctl restart timesyncd
