Given the output of the clock command, this function computes the epoch time, i.e, the time in seconds since January 1,1970 at 00:00:00 UTC. This function is most useful for calculating elapsed times using the clock, and should be accurate to less than a millisecond (although the true accuracy depends on accuracy of the argument vector). The usage for clocktotime is
y = clocktotime(x)
where x must be in the form of the output of clock, that is
x = [year month day hour minute seconds]
Here is an example of using clocktotime to time a delay of 1 second
--> x = clock
x =
1.0e+03 *
2.0120 0.0020 0.0080 0.0220 0.0420 0.0415
--> sleep(1)
--> y = clock
y =
1.0e+03 *
2.0120 0.0020 0.0080 0.0220 0.0420 0.0425
--> clocktotime(y) - clocktotime(x)
ans =
1.0010
