duration is the difference between two datetime objects. So if you know a start date, you can add a duration to it to get the end date. So for example:

>> startdate = datetime(2000, 1, 1);
>> dur = duration(5000, 25, 0);
>> enddate = startdate + dur;
>> enddate
enddate = 
    datetime

As posed, this question is equivalent to, "how do I convert 1 hour to a date?" As SK points out, you also have to answer, "1 hour from what?" And he's provided the solution.

Specific case: It may be that you have durations that represent times of day. If they are all today, for example, then

d = datetime('today') + dur;
