there is a very small number of directives that would require quite a lot of additional code to parse properly. For example, "lastSun" makes a lot of sense as a special keyword in "Rule" directives, but it provides no functional gain in "Zone" directives.
The same holds for the use of the "Dec 29 24:00" time used in Samoa's timezone. We should be able to use "Dec 30" instead, right?
We could, but if the original announcement said the equivalent of "Dec 29 24:00" it's helpful if the corresponding zone line matches the announcement. Similarly, if the Zone transition is supposed to be at the same time and date as a Rule transition, it simplifies maintenance a bit to use the same string for both. As I understand it, in zic the same code is used to parse dates regardless of whether they appear in Rule or Zone lines. I assume the same thing could be done in a Python parser....
