How to to create timestamp from imported data when time data is sperated in three different columns (Month ,Day, Hour)

I am importing wave height data into Matlab to do some análisis. I would like to do a timestamp or represent the time value for each wave height value in some way. However the time data is separated into different columns (Months, Day, Hour). It is not of the format 01-07-2018 9:00. Any ideas? Thank you.

Read about datestr

 d = [2018 03   14   12  0  0] ;
datestr(d)

If Months, Day and Hour are vector with the same length, and assuming Year = 2018, the following can generate datetime vector which is corresponds to the timestamp.

timeStamp = datetime(2018,Month,Day,Hour,0,0);
