PS. If your tzdata parser does not yet support negative DST offsets or 
times past 24:00, or if it insists on a 'pacificnew' file that is no 
longer present, this release's data entries can be turned into a 
rearguard-format tarball that should work even with these older parsers. 
This is intended to be a temporary transition aid for these parsers. To 
generate a rearguard-format tarball, obtain the full distribution as 
described above, and run the command 'make rearguard_tarballs' on a 
development host. Or you can run 'make rearguard.zi' to generate a 
single file that can be fed directly to a parser that works like 'zic'.
