Configuring Date and Time

You configure date and time to help ensure that Operator Display displays the correct date and time.

Operator Display receives date and time from a time master on the BACnet network. In smaller systems where no time master is avaialble, Operator Display can be configured to send its date and time to the connected devices.

Receiving date and time

When Operator Display receives date and time from a time master on the BACnet network, all time stamps in logs are displayed with the date and time received from the BACnet network. Date and time configuration in Operator Display is temporarily applied until the next date and time update from the BACnet network is received.

Alarm time stamps are displayed in Operator Display with the local date and time in the device reporting the alarm.

Note:

If the device reporting an alarm is in a different time zone, Operator Display does not make time zone adjustments.

Configured as a time master

When Operator Display is configured as a time master, it sends its date and time to the connected devices once an hour. Operator Display also sends its date and time when an offline device goes online again and when the date and time is configured in Operator Display.

All time stamps in logs and alarms are displayed with the date and time configured in Operator Display. For more information, see Configuring Date and Time .

Note:

Operator Display does not make Daylight Saving Time (DST) adjustments automatically.

On the BACnet Setup screen, an Operator Display time master is indicated by the Time Master toggle

being dark gray.

Date and Time Administration

As an administrator you configure if Operator Display is the time master and sends its date and time to the connected devices.

Operator Display receives date and time from the BACnet network via the Local Time Synchronization service. The Local Time Synchronization service is configured in the EcoStruxure Building Operation software.

If Operator Display and the connected devices receive their time from the BACnet network, avoid configuring Operator display as the time master. As the time master, Operator Display ignores the date and time it receives from the BACnet network, but the devices receive date and time from both the BACnet network and Operator Display. The latest date and time they receive is applied. For more information, see Configuring Operator Display to be Time Master .

Time and Time Zones

​A time zone is a region on the earth that has a uniform standard time, usually referred to as the local time. Local time is the UTC time plus the current time zone offset for the considered location. Some time zones also have an offset called DST added during the summer period. The DST offset is typically +1 hour.

For more information, see Configuring Date and Time .

Network Time

​Consistent date and timestamping across a network is critical for system wide access control, security, communications, scheduling, alarms, and events. Network time uses the NTP protocol that provides the correct current UTC time.
