Having all source code for all software would be a nice thing, yes. But 
that is also a different issue. :-)

Yes. The program to read RT-11 formatted volumes under RSX is called FLX 
(File exchange), and it will handle dates up to 2099.
FLX also understands DOS-11 formatted tapes, and the date limit there is 
2035.

DECnet DAP protocol have a two digit year specification, and will fail 
in 2069. That is a limit of DAP and will affect *all* DECnet nodes, 
running any OS. The effect is rather limited, though. It will just mean 
that files read over DECnet will indicate the wrong dates for files. 
Nothing really bad will happen because of that.

RSX keeps creation and modification time stamps down to a second.
There is no access time stamp.

In case you switch to using ODS-2 on RSX instead of ODS-1 (the code is 
more or less already there), you instead get timestamps to the accuracy 
of 100ns (if I remember ODS-2 right). Using ODS-2 will also remove the 
2099 date limit that the ODS-1 file system have.

RSTS/E have a file protection. This is a 8-bit field. It encodes both 
access rights, file executable status, and file privilege status.
