Ntp Platform Service Editor Qnx Time Servers
Each entry in the Time Servers list specifies a server to which the host’s clock synchronizes when the service is Enabled (true), and Sync Local Clock to NTP is also true.
This also applies to any
Controls below the list allow you to add 
and delete 
servers, as well as reorder up 
or down 
(to establish priority order, highest at top).
Fields for each time server includes the following:
- Address
Fully qualified domain name, IP address, or host files alias for the NTP time server.
- Peer Mode
Peer mode to use with the server, as either server or peer (symmetricActive).
- Burst
False by default. If true, when server is reachable, upon each poll a burst of eight packets are sent, instead of the usual one packet. Spacing between the first and second packets is about 16 seconds to allow a modem call to complete, while spacing between remaining packets is about 2 seconds.
- Preferred
If true, designates a server as preferred over others for synchronization. Note also that priority order (top highest, bottom lowest) is also evaluated if multiple servers are entered.
- Min. Poll
Minimum poll interval for NTP messages, from 4 to 16. Note units are in “log-base-two seconds,” or 2 to the power of n seconds (NTP convention), meaning from 2 to the 4th (16 seconds) to 2 to the 16th (65,536 seconds).
- Max. Poll
Maximum poll interval for NTP messages, from 10 to 17. Note units are in “log-base-two seconds,” or 2 to the power of n seconds (NTP convention), meaning from 2 to the 10th (1,024 seconds) to 2 to the 17th (131,072 seconds).
