/**
* time - routines for dealing with time
*
* This code provides convenient functions for working with time, in the
* form of 'struct timerel' for durations and 'struct timeabs' for timestamps
* which are light wrappers around struct timespec.

* Example:
* #include <ccan/time/time.h>
* #include <stdlib.h>
* #include <stdio.h>
* #include <err.h>
*
* int main(int argc, char *argv[])
* {
* struct timeabs t;
*
* if (argc != 2)
* errx(1, "Usage: %s <diff in millisec>", argv[0]);
*
* t = time_now();
* if (argv[1][0] == '-')
* t = timeabs_sub(t, time_from_msec(atol(argv[1]+1)));
* else
* t = timeabs_add(t, time_from_msec(atol(argv[1])));
*
* printf("%lu.%09u\n",
* (unsigned long)t.ts.tv_sec, (unsigned)t.ts.tv_nsec);
* return 0;
