+.Os
+.Sh NAME
+.Nm adjtime
+.Nd correct the time to allow synchronization of the system clock
+.Sh SYNOPSIS
+.In sys/time.h
+.Ft int
+.Fn adjtime "const struct timeval *delta" "struct timeval *olddelta"
+.Sh DESCRIPTION
+.Fn adjtime
+makes small adjustments to the system time, as returned by
+.Xr gettimeofday 2 ,
+advancing or retarding it by the time specified by the timeval
+.Fa delta .
+If
+.Fa delta
+is negative, the clock is slowed down by incrementing it more slowly
+than normal until the correction is complete.
+If
+.Fa delta
+is positive, a larger increment than normal is used.
+The skew used to perform the correction is generally a fraction of one percent.
+Thus, the time is always a monotonically increasing function.
+A time correction from an earlier call to
+.Fn adjtime
+may not be finished when
+.Fn adjtime
+is called again.
+If
+.Fa delta
+is
+.Dv NULL ,
+no adjustment is done.
+If
+.Fa olddelta
+is
+.Pf non- Dv NULL ,
+the number of microseconds still to be corrected from the earlier call
+is stored into
+.Pf * Fa olddelta .
+Setting the time with
+.Xr settimeofday 2
+cancels any in-progress time adjustment.
+.Pp
+This call may be used by time servers that synchronize the clocks
+of computers in a local area network.
+Such time servers would slow down the clocks of some machines
+and speed up the clocks of others to bring them to the average network time.
+.Pp
+Only the superuser may adjust the time using the
+.Fn adjtime
+function.
+.Sh RETURN VALUES
+.Rv -std
+.Sh ERRORS
+.Fn adjtime
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EFAULT
+Either of the arguments point outside the process's allocated address space.
+.It Bq Er EINVAL
+The
+.Fa delta
+argument is
+.Pf non- Dv NULL
+and specifies a microsecond value less than zero or
+greater than or equal to one million.
+.It Bq Er EINVAL
+The
+.Fa delta
+argument is
+.Pf non- Dv NULL
+and represents an adjustment greater than
+.Dv INT64_MAX
+microseconds or less than
+.Dv INT64_MIN
+microseconds.
+.It Bq Er EPERM
+The
+.Fa delta
+argument is
+.Pf non- Dv NULL
+and the process's effective user ID is not that of the superuser.

+.Xr date 1 ,

+.Xr ntpd 8
+.Sh HISTORY
+The
+.Fn adjtime
+function call appeared in
+.Bx 4.3 .
+.Sh CAVEATS
+Other operating systems restrict calling
+.Fn adjtime
+to the superuser and might not allow requesting the current
+correction without specifying a new value.
