Wrong Conversion problem from datenum

In a Serial data receiving process, I have a incoming data

press = {'2016-04-14'    '14:18:48'    '321'};

datenum(datestr(cellfun(@(x,y) [x y],press(1),press(2),'un',0)));

Here, the result of date time serial from above step,

ans = 7.3648e+05

When I convert back, the result is giving a different time into the future:

datestr(ans)

ans = 29-May-2016 22:18:48

where this is working wrong?

Look at the char array you're creating with your cellfun call.

>> q = cellfun(@(x,y) [x y],press(1),press(2),'un',0)
q = 
    '2016-04-1414:18:48'

It looks like somehow datestr is interpreting your string with format 0 (as described in the help text) and treating the 1414 part as a number of days somehow. You can correct this by adding in the missing space:

>> q2 = sprintf('%s ', press{1:2})

I would also recommend that if you're using a release that contains the datetime function that you avoid using serial date numbers and create a datetime instead.
