The clock tab is used as the main point of reference for determining the time and status of a clock as well as providing information about the unit itself.
The time section of the Clock tab shows the current UTC time and date as well as the Local Standard Time (LST) and date (user configurable) that is being output by the connected clock.
By clicking on each of the time displays, you are able to change the display type to either display the time in, 12H, 24H or analogue formats.
*if the clock display shows "Time not available" or a different date to the current date instead of valid time, the clock is either in the process of start-up or does not have a sync source.
The localization settings of the configuration software will allow you to configure your current time zone and UTC offset.
The next section allows you to configure daylight savings time, if and when your region observes daylight savings. The configuration software allows you to configure how much of an offset the daylight savings shift is, if it is observed on the same day every year, and then it allows you to configure what days it begins and ends on.
Tekron clocks are capable of synchronising to multiple different time sources, including GNSS, IRIG-B, PTP and NTP. The Clock Source Priority section shows the priority list for which valid time source to synchronise to. The user is able to configure this sync source priority list by dragging the preferred source to the top of the list. The top of the list is considered the highest priority, whereas the bottom of the list is considered the lowest priority.
The clock will automatically adjust to the preferred time source if the current time source if lost, and will then automatically switch back when it is regained. This is unless the override quality checkbox is ticked, in which case the top priority source will stay as a top priority regardless of accuracy.
The system information section is used to provide at a glance look at the clock, including its Status, Model, Product/Order Code, Serial Number, UTC -> TAI offset and the Firmware (Clock, Ethernet/Net, GNSS Version).
The status indicates the current sync status of the clock
These are the sync status values:
|Synced(GPS)||Clock is synced to GPS constellation|
|Synced(GNSS)||Clock is synced to at least one of the available constellations|
|Synced(IRIG-B)||Clock is synced to an external IRIG-B source|
|Synced(PTP)||Clock is synced to an external PTP source|
|Synced(NTP)||Clock is synced to an external NTP source|
|Synced(TEST)||Clock is in test mode and has been set with an arbitrary time|
The clock name is the clock designation as configured in the maintenance tab.
This is the username of the current user logged in.
This is the model of the clock is being configured.
This is the product code of the clock is being configured.
This is the serial number of the clock is being configured.
This is the serial number provided to the particular Ethernet module on the clock, that is being configured.
This is the firmware that is running on the main board of the clock.
This is the firmware that is running on the particular Ethernet module on the clock, that is being configured.
UTC -> TAI offset
This indicates the current number of seconds between TAI and UTC as used by the clock.
GPS version/ GNSS version
This indicates the version number of the firmware running on the GNSS receiver module.
This indicates the type of oscillator installed on the clock.
