Date & Time

Configure the gateway date and time through Clock settings. You can set the date and time either manually or by Network Time Protocol (NTP). Setting to NTP helps eliminate uneven calibration of time between devices. To configure the NTP server, see NTP Configuration Settings.

Setting the Date and Time

To set the date and time, perform a Clock status action.

In Web Manager, go to Clock, then click Set.

CLI settings: See Status Clock level

XML settings: See statusgroup Clock

Clock Configuration Settings

The following table describes the Web Manager Clock configuration settings.

Links to the equivalent settings for the CLI and XML reference are listed below.

CLI settings: See Config Clock level

XML settings: See configgroup clock

Clock Settings	Description
Source	Either Manual or NTP.
Manual	Command to set the source to Manual, meaning the time and date are entered manually by the user. The format for setting time is YYYY-MM-DD hhss, where the hours are in 24-hour format. The gateway supports dates in the range of 2000-01-01 00:00:00 to 2100-12-31 23:59:59 UTC. Manual is the default source setting in Clock.
NTP	Command to set the Source to NTP to synchronize the date and time to the UTC official standard for current time.
UTC Offset	Command to specify the UTC offset in minutes between the range of -1440 and 1440. List of common time zones and corresponding UTC offsets can be found at several websites, including the IANA Time Zone Database or the Wikipedia list of UTC time offsets. Offset to UTC is specified in minutes, between the ranges of -1440 and 1440 and can be up to 5 characters. If the time source is set to manual, the current time can be set with the "Current Time" status (set) action.

NTP

Network Time Protocol (NTP), is an Internet protocol used to synchronize computer clocks to an official standard for current time. The Simple NTP (SNTP) client is used to support Clock when it is set to NTP. When configured as the time Source, NTP will update the clock from the configured NTP server according to the frequency you set.

Use the NTP group to configure the NTP server hostname and sync time frequency. You can also initiate an immediate clock synchronization with the NTP server.

In Web Manager, go to NTP. Click Configuration or Status to configure the NTP server or view the NTP status and optionally, synchronize the clock with the NTP server.

In the CLI, see Config NTP level and Status NTP level.

In XML, see configgroup NTP.

The XML does not support the NTP Sync command.

NTP Configuration Settings

The following table describes the Web Manager NTP Settings configuration settings.

Links to the equivalent settings for the CLI and XML reference are listed below.

CLI settings: See Config NTP level

XML settings: See configgroup NTP

NTP Setting	Description
Sync	Command to manually sync the Clock to NTP. This appears on the Status page.
Server Hostname	NTP command to enter the name or IP address of the NTP server (e.g., pool.ntp.org). May contain 128 characters.
Sync Time	NTP command to set the Sync Time in seconds, minutes and/or hours (e.g., "8 hours"). After a successful update, the NTP client waits the indicated Sync Time before querying again.
