--	**NTP and accurate time:** If you are not using Amazon Linux (which comes preconfigured), you should confirm your servers [configure NTP correctly](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-time.html#configure_ntp), to avoid insidious time drift (which can then cause all sorts of issues, from breaking API calls to misleading logs). This should be part of your automatic configuration for every server. If time has already drifted substantially (generally >1000 seconds), remember NTP won’t shift shift it back, so you may need to remediate manually (for example, [like this](http://askubuntu.com/questions/254826/how-to-force-a-clock-update-using-ntp) on Ubuntu).
