On my (long) list of things to do is to make a thread-safe version of the glibc version of the tz library. Once you know you're dealing with that particular library, the job becomes tractable.
FreeBSD includes a reentry-preventing version of the timezone code. Granted, this is not an ideal state of affairs, but it does allow people to call localtime() in their threaded C programs. (The library simply puts a global lock wrapper around all the time functions that examine the zone structure.)
There is a reentrant implemetation in Solaris (except tzset() and tzwall()), but it is not enough for a complete solution, as you perhaps understand. I have requested Sun's opinion before tinkering with the code. Thanks again, Valery
