.SH NAME
\f4difftime\f1 \- computes the difference between two calendar times
.SH SYNOPSIS
\f4#include <time.h>\f1
.PP
\f4double difftime (time_t time1, time_t time0);\f1
.SH DESCRIPTION
.PP
\f4difftime\fP computes the difference between two 
calendar times. \f4difftime\fP returns
the difference \f2(time1-time0)\f1 expressed in seconds as a \f4double\f1.
This function is provided because there are
no general arithmetic properties defined for type \f4time_t\f1.
.SH "SEE ALSO"
\f4ctime\fP(3C).
