There is no definite schedule for that, just as there is no definite 
schedule for anything associated with tzdb. It's a volunteer effort, 
after all.

That being said, you needn't retrieve a rearguard-format tarball to get 
rearguard-format data. You can instead use the ordinary tarball, which 
comes bundled with software that will generate rearguard format upon 
request. Even if I stop my informal distribution of a rearguard-format 
tarball, you can still generate rearguard-format data from the standard 
distribution by running the command 'make rearguard.zi'.

I also suggest boosting the priority of updating your custom version of 
tzcode so that it works the way ordinary tzcode works. tzcode's zic has 
supported negative offsets for decades, and it's time to catch up.
