I know there are some configuration options in webmin, but it's been a long time since I've tried to customize webmin.

After poking around the webmin directory, it appears that the tab can be hidden by modifying the defaultacl.

A consistent and accurate time reference is crucial for many server tasks and processes.

Webmin seems blissfully unaware of the existence of ntpd.

The 'Time server sync' tab on the System Time page allows ntpdate, if it is present, to be run periodically, probably via cron.

The -g and -x options can be used with this option.

Note: The kernel time discipline is disabled with this option.

If you use the AWS CLI or an AWS SDK to make requests from your instance, these tools sign requests on your behalf.

If your instance's date and time are not set correctly, the date in the signature may not match the date of the request, and AWS rejects the request.-g Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default.This option allows the time to be set to any value without restriction; however, this can happen only once.In addition, your instance's security group rules must allow outbound UDP traffic on port 123 (NTP), and your network ACL rules must allow both inbound and outbound UDP traffic on port 123.The procedures in this section show how to verify that the default NTP configuration is working correctly.I have just run into an issue with Dovecot that killed itself because of a backward time sync. Unfortunately, we've since discovered that ntpdate is a necessary evil.
