It's a Linux issue. Solaris gives:
> Sys.time()
[1] "2003-03-06 08:27:23 GMT"
> as.POSIXlt(Sys.time(), "HST")
[1] "2003-03-05 22:27:40 HST"
which looks right to me. Past experience suggests that Solaris's POSIX
conformance is much better than glibc's. Since my RH7.2 box does it too,
I will look for a workaround. (The problem seems to be in the use of
tzset, and the code of zdump may indicate how to get around this.)
