Perhaps I should clarify my question here. [:) I'm far less concerned 
with RTC roll-over as I am with whether the O/S will be able to 
accurately report dates beyond 31 December 1999. [:) Do you know of 
_any_ versions of OS/2 which will have trouble doing that?

I've no wish to begin a thread/discussion or to argue with you, but just 
for the sake of expressing a point of view, I disagree with the point of 
view of there being a "bug" in so-called "older hardware". My point of 
view here is that since the limitations of the RTC were well-known at 
the time it was implemented into the AT, and that since this limitation 
was well-known to those who implemented the BIOS, and that since both 
the RTC and the BIOS are both performing exactly the way that they are 
intended and expected to, that there is no "bug".

JMO. [:)


ML> The basic OS/2 operating system (at least since Warp 3) takes care
ML> of "buggy BIOS" machines, and the OS/2 system clock (which is the
ML> RTC, not a separate set of counters) will not die until the end of
ML> 2079 ("end of time" for OS/2 as presently written).

Is this true of _all_ versions of OS/2, that they all use the RTC for 
for their TOD clock? (Is the 2079 a C thing?)


ML> However, there is
ML> an IBM Web site that might answer your questions:
ML> http://www.ibm.com/software/year2000/alert/

Thanks for the tip. Take care and TTYL.
