c={'22.11.2011 13:58:56.16','22.11.2011 13:58:40.16'};
d=datevec(c);
floor(d(:,6))

If you have strings of dates, use datevec as follows:
[Y, M, D, H, MN, S] = datevec('22.11.2011 13:58:56.16');
You'll notice that S has the value "56.1600", so floor(S) gives you the seconds

out = datevec({'22.11.2011 13:58:56.16'},'dd.mm.yyyy HH:MM:SS')
out = out(end)
OR
out = sprintf(':%d',out(end))

> datestr(datenum({'22.11.2011 13:58:56.16'},'dd.mm.yyyy HH:MM:SS.FFF'),':SS')
ans =
:56
>> char(cellfun(@(T) T(end-5:end-3), {'22.11.2011 13:58:56.16'},'Uniform',0))
ans =
:56

Based upon the previous answers, the following should also work:
datestr(datevec({'22.11.2011 13:58:56.16'}),':SS')
