20 The \fBdifftime()\fR function computes the difference between two calendar
25 The \fBdifftime()\fR functions returns the difference \fI(time1-time0)\fR
26 expressed in seconds as a \fBdouble\fR.
30 The \fBdifftime()\fR function is provided because there are no general
31 arithmetic properties defined for type \fBtime_t\fR.
