I recently looked at your excellent time package. However, it appeared to me that if someone in a foreign country got a copy of a machine with this code, that they would have a hard problem figuring out what TZ to use, as they are not enumerated in ctime.3 (at least in my copy), nor did there appear to be any tools to build such a file from the /etc/zoneinfo directory. My question is thus: have you developed a program that walks the directories, and builds a table of the available entries? The way we intend to solve this for SunOS 4.0 is to give a listing of the various TZ values, and the areas to which particular values apply, in the "installing SunOS" documentation.
