Give the time in seconds between two scans for new or dropped interfaces.
313
For systems with routing socket support the scans will be performed shortly after the interface change

has been detected by the system.
315
Use 0 to disable scanning. 60 seconds is the minimum time between scans.

descrip = "Slew up to 600 seconds";
423
Normally, the time is slewed if the offset is less than the step threshold, which is 128 ms by default, and stepped if above the threshold.
424
This option sets the threshold to 600 s, which is well within the accuracy window to set the clock manually.
425
Note: Since the slew rate of typical Unix kernels is limited to 0.5 ms/s, each second of adjustment requires an amortization interval of 2000 s.
426
Thus, an adjustment as much as 600 s will take almost 14 days to complete.
427
This option can be used with the
434
configuration file directive for other options.
435
Note: The kernel time discipline is disabled with this option.
