? I think you are recalling this one
http://www.vaxmacro.de/vbto.html
? that explains when VMS clocks will overflow. We have a little while
left before that's a problem.
? There will be other problems when the year increments to 5 digits,
but the above article assures us that there will be a fix before then...

Ah. Found it:

But I thought it also mentioned when the VMS timestamp would run out,
but I seem have misremembered. But anyway, it does show that DEC had
already thought about beyond 2000 back in the early days of VMS.

Now someone just need to post the link to the
answer written by
someone at DEC about the eventual wrapping of the VMS timestamp.
Time in VMS is handled pretty nicely. The only real problem is that
they went with local time. Otherwise the VMS timestamp is excellent.
(I think TOPS-20 use the same thing.)

While I'm sure there were various Y2K bugs around, the basic design
in VMS was intended from day 0 to handle dates beyond Y2K.
So I would just try to set the correct date to start with, and if
something seriously breaks, then I would consider shifting it back
to an earlier year.
Oh... I set the time and date when prompted during the
installations, and then when the system time displayed as 1982, I
assumed it was not Y2K capable. So I tried setting the time after
booting:
$ show time
??? 8-DEC-1982 17:39:46
$ set time=08-DEC-2021:17:40
$ show time
??? 8-DEC-2021 17:40:02
And then after rebooting:
?? VAX/VMS Version V3.0 26-APR-1982 16:21
%OPCOM,? 8-DEC-2021 17:42:34.01, logfile initialized by operator OPA0
???????? logfile is SYS$MANAGER:OPERATOR.LOG

???????? Welcome to VAX/VMS version V3.0
$ show time
??? 8-DEC-2021 17:42:53
How about that!
