  28   29  .LP
  29   30  \fBddi_get_time()\fR returns the current time in seconds since 00:00:00 UTC,
  30      -January 1, 1970. This value can be used to set of wait or expiration intervals.
       31 +January 1, 1970. Changes in time of day clock may result in this value
       32 +changing. In other words, the value is not monotonically increasing and
       33 +therefore it must not be used to set wait or expiration intervals. For that,
       34 +instead use \fBddi_get_lbolt\fR(9F) or \fBgethrtime\fR(9F).
