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]
clocktotime
to time a delay of 1 second
