standup.bash chrony for time synchronization

[poroburu]

I'm following Notional's wonderful guide for closet validation. While setting up a Juno node, it requested chrony as part of the toolchain.

I cross referenced with the standup.bash file to learn more. I found that it used systemd-timesyncd instead.

Doing a quick search revealed this Stack Exchange thread. It seems that chrony is more accurate and has smoothing algorithms to avoid time jumps.
