Do you have reason to believe that people still use version-1 TZif files? As far 
as I can recall, only Android limits itself to 32-bit timestamps (expiring in 
2039) among current operating systems, even the 32-bit OSes. However, Android no 
longer uses separate TZif files and instead bundles up tzdata as part of a 
single larger file somehow.

I don't know where this stuff is written down; it's merely part of my vague 
recollection and could be incorrect.
