method for converting seconds from date to datetime

Is there a method in matlab to convert seconds from a known date to a standard date time format?

For example, if I have a vector of values shown as seconds from 1901/01/01, how would I convert them to a dateTime? In this case a value of 28125 would correspond to 1981/01/01. Is there an efficient method for doing this?

The numbers in your example do not make sense so it is not clear if your time is in seconds or days but since you asked for seconds I will use this.
What you want to achieve can be done using datenum function. This function returns the number of (fractional) days from 1/1/0000. So first you need to find your offset, e.g.: 

offsetInDays = datenum(1901,1,1);

Next, you convert the date from seconds to days: 

dateInDays = YourRequiredDateInSec * 3600 * 24;

Finally, you date is given by 

RequiredDate = datestr(offsetInDays + dateInDays);
