There are also OS's that don't maintain a time-of-day clock, but the
time() function is standard. The same logic should apply here. If the OS
doesn't know the answer, it should return some sort of distinctive value
for the timestamp (e.g. zero). I think file timestamps would be a very
worthwhile addition to the standard library.

Is there an ANSI C++ "standard" way of retrieving the date and time of
a file?  I usually use "stat", but that is not standard.  Thanks,

No.  There are, in fact, OS's that don't maintain this information, so
the standard doesn't require it to be made available.
