I have data files time tagged with C standard "time_t" data structure, which I believe is just time in seconds after 1 Jan 1970 (I don't care about variations of leap seconds included).  I cannot find any direct Matlab conversion function that seems appropriate, or actual C coding to perform the conversion (only references to the C function call "ctime").  This seems like it should be a simple thing, but I can't find anything that works.

Maybe you cannot find anything because it is simply one line:
t=3Ddatenum(1970,1,1) + ctime/86400;
