Does it exist a function which is similar to time() function of C ambient ?

Hi, i'm working with random number generation, I would like to know if exists, in Matlab, a function like time(0) of C ambient (like emacs) which gives the number of seconds from a certain day.

The number of seconds of the current day:

s = rem(now, 1) * 86400;

Number of seconds since 17-Mar-2011:

s = (now - datenum('17-Mar-2011')) * 86400;

This does not use the modern datetime object.

For datetime:

 s2 = seconds(datetime('now')-datetime(2011, 3, 17))

Or for that matter,

>> round(posixtime(datetime('now')))
ans =
                1507893971
