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
