I have tested 2.6.3 on my Debian Sarge box w/rsync 2.6.3, and I cannot
reproduce this (yes, my clock is set to UTC).  I normally have "TZ"
defined in my environment ("PST8PDT"), but unsetting this had no effect.
I tested both syslog and direct logging.

Note that rsync does nothing to manipulate the timezone directly, but it
does ensure that log_init() is called prior to calling chroot(), and
this ensures that one call to localtime() occurs before the chroot()
(which should load the timezone for any future calls) and that openlog()
gets called (to initialize any syslog() calls to follow).

FYI, *both* those log lines get output *after* chroot() gets called.  So
there has to be something else besides chroot() that is the real culprit
in the loss of the timezone on this system.  I'd recommend upgrading to
2.6.3 and see if the problem persists.  If so, the only other thing I
can think to try is to run the daemon under something like valgrind and
see if it reports any memory-access problems on your system (you might
want to try this with the current 2.6.3pre1 too):

    valgrind rsync --daemon --no-detach

I've run this command in my setup, and it reports no errors.
