General
Parameter | Description |
---|---|
Enable daylight saving time | Select to use daylight saving time (DST). Note: Services such as syslog that timestamp events with the current time and date are affected during DST transitions. As such, you may observe 60-minute gaps or duplicate timestamps around the time when the clock was changed. |
TAI offset | The offset to add to UTC time to convert to Temps Atomique International (TAI)—atomic international time. In early 1972, TAI was exactly 10 seconds ahead of UTC. From 1972 until June 30, 2015, 26 leap seconds were added to the difference. Since the last second was added on December 31, 2016, TAI has been exactly 37 seconds ahead of UTC. It is important that the TAI offset value be consistent throughout your network in order to ensure valid measurements and avoid synchronization issues. This is particularly true if Accedian products are being used with equipment from other vendors that support leap seconds. If there is a TAI mismatch between units, the one-way delay measurements will show an offset of one second. In most cases, it is preferable to allow the unit to update its TAI offset value through a firmware upgrade (during a maintenance window to minimize impact) instead of manually changing the value here. |
Clock name | On the Skylight sensor: control units, it is possible to set up Time of Day (ToD) clocks. Use this parameter to select a clock that is available on the unit being configured. It is possible to use a configuration job to set up a clock on a Skylight sensor: control. See "Setting Up a Clocks Configuration Job". |
