Time for NTP

NTP

It's important that ALL the servers within the Knocknoc cluster and agents are synchronised and set to the correct time. 

We recommend using chrony on a Linux VM to keep the time, but any NTP implementation would work. Time is an important aspect of authentication, and users are authorised for a time window that is correct for the current time, relative to now. Hence, please keep all the servers time-correct.

Time sync is also crucial for TOTP to work effectively.
