There is no alternative. seconds() creates a duration datatype, but that datatype did not exist in your release.

If you switched over to using serial date numbers, then you could define

seconds = @(x) x/(24*60*60);

but you would only be able to use it in limited circumstances, such as

t = now;
datestr(t)
datestr(t + seconds(180))
