In the version of elm distributed with redhat 5.2, the current year (2000)
is stated as "100" when you send a message.  This problem seems not to
exist in the redhat 6.0 elm.  The source code fix is undoubtedly trivial
(change a "tm_year" to "tm_year+1900" somewhere, to use four-digit years).
Alternatively just compile elm 2.5x for glibc 2.0 or whatever it takes to
make it able to run on a redhat 5.2 system.  The elm "errata" rpm for 5.0
(and 5.1?) seems to be the same as the redhat 5.2 distributed rpm, namely
elm-2.4.25-14; so this also applies to redhat 5.0 and can hopefully use the
same bugfix rpm.  Presumably redhat 4.2 has the same problem too, if you're
still supporting that.

Let me know if you'd like me to track down the appropriate "tm_year" in the
source code, if you want to go that route rather than the 2.5x route.  (I
assume this will be trivial upon investigation but I'm happy to do it if it
turns out not to be.)

thanks,
