The Allegro Network Multimeter can be configured to use a time synchronization service. NTP is supported for all variants of the Multimeter. PTP service may be used if management interface supports hardware time stamping. | The Allegro Network Multimeter can be configured to use a time synchronization service.

To enable a time service, switch to the proper type in the dropdown box. The time service field will show whether the selected service is running or not. | |||
For NTP time retrieval you can specify and edit dedicated NTP servers. If you do not specify a NTP server, a set of predefined NTP servers will be automatically selected. | |||
For PTP time retrieval, the PTP grandmaster clock identity is shown. This is usually an EUI-64 address. The first and last set of octets of the identity represent the (EUI-48) MAC address of the grandmaster. | For PTP time retrieval, the PTP grandmaster clock identity is shown.

The GPS time retrieval option is available if a GPS capable PTP grandmaster card is installed in the Multimeter. | |||
NTP from data plane can be used to retrieve the time to be synchronized passively from NTP packets of the analyzed traffic. The IP address of the desired NTP server must be set. As soon as a NTP server packet is seen the system time of the Multimeter will be set. The wait period field can be used to set a time period where subsequent updates are ignored. If set to 0, every time packet of that server will be used. | |||
If no time synchronization mechanism is selected the date and time of the device can be manually configured by entering a properly formatted date and time description. | If no time synchronization mechanism is selected the date and time of the device can be manually configured by entering a properly formatted date and time description. | ||
Below the time synchronization settings, the time zone used by the device can be configured. The drop-down list provides a list of cities grouped by world regions to select the appropriate time zone. | Below the time synchronization settings, the time zone used by the device can be configured.
