Configuring date/time on the appliance

There are two ways to set the time on the appliance.

Method 1: Synchronizing with NTP

Newer appliances have been updated to include a daily cron job (scheduled task) to sync the date/time setting.

  1. To enable advanced options, enter http://<applianceip>/setadv.php in the browser address bar, and set the flag to enabled¹.
  2. Navigate to System Status – ADV Shell Scripts.
  3. Enter the following, and click Submit:

yum install ntpdate -y
echo ntpdate > /etc/cron.daily/ntpdate
chmod 755 /etc/cron.daily/ntpdate

Method 2: Manual entry of date/time

1. Follow the above instructions to get to ADV Shell Scripts.

2. Enter the current date and time manually, using the following format

date -s “ddMMM YYYY HH:mm:ss”

3. Click Submit.


¹ For version 6.8.3a and earlier, the shell-script executor is located in the hidden menu. In the browser address bar, enter http://<applianceip>/admin/hidden.php. In the Appliance section, select Shell Script Executor. Enter the commands above.
