dump of compiled timezone files

[Reinhard]

Hello,

I want to compare an older version (debian sarge) of the compiled timezone 
database with a newer version (debian etch). So I'm looking for a utility that 
dumps the contents of a compiled timezone file in human readable format the can 
be compared by utilities like diff or tkdiff afterwards. Can I use a timezone 
db compiled for etch on a sarge machine?

Thanks
Reinhard
