} I sorta doubt *any* unix application will have year 2000 problems. Times

The real problem is date parsing.

I know of no time, or any reason, that means that exim ever has to parse
and convert a date from user form into internal form, so 2 digit years
should never be a problem.

Exim always generates dates in 4 digit year form, so anything parsing its
dates should also be OK. MUAs that generate 2 digit year dates will not
have them fixed by exim, which is pretty much how it should be.

However, without modification of both exim and the underlying operating
system, there is likely to be serious problems around 2038 when the
seconds count runs out of steam on 32 bits. I intend to have retired by
then :-)
