13.3.29.2 NTP Association

Network Time
The interaction between the access point and an NTP server constitutes an association. NTP associations can be either peer
associations (the access point synchronizes to another system or allows another system to synchronize to it), or a server
associations (only the access point synchronizes to the NTP resource, not the other way around).
To view the access point's NTP association statistics:
1. Select the Statistics
2. Select System
connected access points.
3. Select Network Time
4. Select the NTP Association
Displays the precision of the time clock (in Hz). The values that normally appear in this field
range from -6, for mains-frequency clocks, to -20 for microsecond clocks.
Displays the time stamp the access point's clock was last synchronized or corrected.
Displays the address of the time source the access point is synchronized to.
The total round-trip delay in seconds. This variable can take on both positive and negative
values, depending on relative time and frequency offsets. The values that normally appear in
this field range from negative values (a few milliseconds) to positive values (several hundred
milliseconds).
The difference between the time on the root NTP server and its reference clock. The reference
clock is the clock used by the NTP server to set its own clock.
Displays how many hops the access point is from its current NTP time resource.
