I do now that several years ago Oracle did not release a Java update that included the TZdata updates for a change in Timezone information until 72 hours after the change went into affect.

Large companies like Oracle, Microsoft, etc. move as fast a Governments.

I think we should expect that these economics and timing of timezone information authority, packaging, and distribution will change if the Time Zone Data Distribution Service (tzdist) becomes a widely implemented standard.
Changing the distribution of the information from OS updates to on-demand web service may mean that the IANA efforts of this mail list, Apple, Microsoft, Google, etc.  will all have to decide how they want to fit into that new model of "publishers" and "providers".
This current discussion about Uruguay seems to be leading toward that process.
