I don't know what olr.day.mean.nc is. What makes you think it is equivalent to a MATLAB datenum?

I did a search for it. Go to NOAA Daily (non-interpolated) Outgoing Longwave Radiation (OLR) and find appropriate software to read the files. Another possible source of information is Re: Rewriting nc files.
Have fun!

Thanks to Star Strider's investigative work, I found this page that says that the OLR value is the number of hours since 1-1-1 00:00:00. This suggests to me that your conversion should be
datestr(17298624/24+365)
That's a few days off from the date you specify, but it is close.
