Expected lifetime of software?

[Hal Murray]

How long do we expect our code to last?  Or perhaps more importantly, how 
long do our users expect it to last?

If the time stamp on the wire wraps in 2036, how far back do we have to get 
ready and/or when should we start announcing that we are or are/not ready?

2036 is only 20 years from now.  That's the same time span as the GPS 1024 
week roll-over, and there is plenty of old GPS gear that is still working and 
old enough to hit that limit.
