d = [1992.752225; 1992.765914; 1992.779603; 2018.460643];
datetime(floor(d), 1, 1) + years(mod(d,1))
ans = 4×1 datetime array
   01-Oct-1992 17:52:08
   06-Oct-1992 17:51:51
   11-Oct-1992 17:51:34

However, I would be concerned about the difference between years() -- which uses fixed-length years -- and calendar years. 
fd = floor(d);
datetime(fd, 1, 1) + (d-fd) .* days(365+leapyear(fd))
ans = 4×1 datetime array

   07-Oct-1992 07:47:18
   12-Oct-1992 08:01:57

The similarities of the first three times in the first version suggest to me that the time system is using fixed length years --- but that can make it difficult to figure out how to handle the leapyear. Some time systems like that just remove the leap day; if you are using one of those then for entries for which leapyear() is true and the date is after Feb 28, you have to add one day.
