The Gateway has a terminal user interface for configuring time, time zone, and time synchronization. It may be desirable to manage these items outside of the Gateway configuration menu. Additionally, development incident SSG-4589 exists to address some concerns regarding certain behaviors of this configuration menu. In order to accommodate for these behaviors, certain items can be manually configured.


Component: APIGTW


The Gateway configuration menu provides a TUI-based front-end for several Linux applications that are used to configure the system. This includes but is not limited to: System time, system time zone, and the network synchronization configuration. To configure each of these items manually, follow the associated procedures:

System time and date

Set the date and time in the following format: "DD MMM YYYY HH:MM:SS" For example: date -s "2 OCT 2006 18:00:00"

Local system time zone

The Gateway appliance contains various files that associate with specific time zones. These files are contained in /usr/share/zoneinfo. A Gateway can be configured to use these time zone files as follows: ln -sf /usr/share/zoneinfo/path/to/zone /etc/localtime. For example: ln -sf /usr/share/zoneinfo/US/Eastern /etc/localtime

Network time synchronization

Adjust NTP runtime status

An administrator can start, stop, restart, or query the current running status of the NTP client as follows:
  • service ntpd status
  • service ntpd stop
  • service ntpd start
  • service ntpd restart

An administrator can also configure and query the running state of the NTP client upon system initialization:

  • chkconfig --level 2345 ntpd on
  • chkconfig --level 016 ntpd off
  • chkconfig --list | grep ntpd

The NTP client can be manually synced the remote server

  • service ntpd stop
  • ntpdate -v
  • service ntpd start

Particular servers can be added to the pool of servers by reconfiguring the NTP client configuration file (/etc/ntp.conf) to have one or more of the following directives:

  • server
