NTP ModuleView SourceRelease Notes
This module installs and configures Chrony on a Linux server. This helps prevent clock drift on the server; if the clock drifts too far, you'll get all sorts of strange errors, such as AWS API calls failing due to invalid timestamps.
This script currently works on:
- Amazon Linux and Amazon Linux 2 (currently a no-op, since Amazon Linux already has NTP installed & configured)
Why does a module called NTP install something other than NTP?
Originally, Amazon recommended installing
ntpd to prevent clock drift. Today, Amazon recommends Chrony. In addition, Chrony is a newer, more robust implementation of the network time protocol (NTP). Chrony is strongly preferred to ntpd, however there are still minor differences between ntpd and chronyd.
