Time Synchronization
From Hack Manhattan Wiki
casey is the master time server. Like the other nodes, it runs chrony.
casey has DS3231 real time clock chip attached to its GPIO pins. Fedora has the drivers, Debian does not. Hence why its on casey and not april.
There is a Ansible playbook set-time-zone.yaml that set the timezone to America/New York and sets the hardware clock to UTC, applied to all hosts.
