Platform Service Properties (platform-NtpPlatformServiceQnx)
This controller component is the Niagara interface to the NTP (Network Time Protocol) daemon of the QNX OS running on a controller. If enabled, it provides client and server support for NTP.
The default view of this platform service is the Platform Service Properties view, in which you can adjust a few settings, as well as specify time servers.

| Property | Value | Description |
|---|---|---|
| Platform Service Description | read-only | Reports the type of service. |
| Enabled | true (default) or false | Enables and disables the use of the Network Time Protocol
in the controller. true causes the host to use NTP to sync its clock with time values retrieved from other servers. |
| Time Servers | additional properties. | Additional properties. |
| Statistics | read only (defaults to false) | Indicates if statistics are available. true reports information about NTP operation. |
| Ntp | read only (defaults to true) | Reports if NTP (Network Time Protocol) is enabled. |
| Local Backup | read only (defaults to false) | Reports how server polling is handled. true indicates that if the specified NTP server(s) become unavailable during a poll, the system clock provides the time used. This prevents the timing of the polling algorithm in the ntpd (which is executed at specified/changing intervals) from being reset. A true value does not change the NTP daemon’s polling interval (frequency). In fact, by using the local system clock, the NTP-calculated polling time would remain the same and thus not result in more polling. |
| Sync At Boot | read only (defaults to false) | Reports if the local system time should be updated at platform
boot. true executes the ntpdate command to update system local time when the controller boots. This happens before the station starts or the ntpd starts. |
| Host Mode | read-only | Indicates that this host acts as an NTP client only. The NTP data retrieved by this host from configured servers is not available to local network devices. |
