KNOWN BUGS & ISSUES
===================

Memory leak under Mac OS X 10.2 and FreeBSD

    This module relies on the tzset(3) system call to change the
    local timezone. The only way to control input to the tzset(3)
    call is by setting the TZ environment variable. Unfortunatly,
    the setenv(3) system call leaks under FreeBSD, and Mac OS X 10.2
    inherited this bug. This is documented as a bug in the man pages of 
    both operating systems.

Not quite thread safe

    The current local timezone is global to the application. As we need
    to redefine what the local timezone is, there is a small window
    where calls to time.localtime, time.mktime, time.ctime or time.strftime
    will do their calculations with incorrect time zone information.
    The PosixTimeZone class uses a lock to avoid this situation, but this
    lock is not shared with the existing time module.
