Time

Current Time and Date

• Date: The current date.
• Time: The current time.
• Apply PC Time and Date Now: When selected sets the current date and time to that of the PC being used.

Network Time

• Automatically Synchronize with an Internet Time Server: Select this option to automatically synchronize the controller with an internet time server.
• Primary SNTP Time Server: IP address of the primary SNTP time server for the controller to update its time from.
• Secondary SNTP Time Server: IP address of the secondary SNTP time server for the controller to update its time from should it not be able to connect to the primary SNTP server.
• Time Zone: The current time zone that should be assigned to the controller. Offset from GMT.

When using a time server the time provided is always in UTC (Coordinated Universal Time), which has no time zone and is not subject to any daylight saving time rules. This means that you must correctly configure the time server, the time zone that the controller is operating in, and the daylight savings settings for the time to be synchronized correctly. Failure to configure any of these will result in the time being inaccurate.
