 The \fBadjtime()\fR function adjusts the system's notion of the current time as
 returned by \fBgettimeofday\fR(3C), advancing or retarding it by the amount of
 time specified in the \fBstruct\fR \fBtimeval\fR pointed to by \fIdelta\fR.

 The adjustment value will be silently rounded to the resolution of the system

 .SH RETURN VALUES

 Upon successful completion, \fBadjtime()\fR returns \fB0\fR. Otherwise, it
 returns \fB\(mi1\fR and sets \fBerrno\fR to indicate the error.
