ntptime [-chr] [-eest_error] [-ffrequency] [-j] [-mmax_error] [-ooffset] [-sstatus] [-ttime_constant]
4. Description
Checks the kernel configuration for the NTP user interface
syscalls ntp_gettime() and ntp_adjtime(). If present, the current
timekeeping data are displayed. If not, a disappointment is
displayed. See the kernel page file in the HTML documentation in
distribution for further details.
A similar display can be obtained using the ntpq program
and kerninfo command.
This program is useful only with kernels featuring the ntp_adjtime(2) system call or local equivalent, as described in the A Kernel Model for Precision Timekeeping page,
