TZ bug

[David Robinson <dr...@ast.cam.ac.uk>]

Apache does not pass the TZ enviromnent variable to CGI scripts, so that
the OS date routines are likely to get the timezone wrong. Here is a patch
to 0.8.16:

    Subject: Fix big in system time routines in CGI scripts
    Affects: util_script.c
    ChangeLog: Pass TZ environment variable to CGI scripts
