[kronolith] Timezone problem, with patch

[Chuck Hagenbuch]

Quoting Kevin Ross <Kevin@FamilyRoss.net>:

> I have traced the problem to kronolith/lib/base.php, where it sets the
> TZ environment variable.  The problem is, when the option is "Use
> default", it sets the variable equal to an empty string, rather than
> leaving it unset.  This causes the C function tzset() to use GMT instead
> of local time (see tzset(3) for more info).

Fixed in HEAD and RELENG_1, thanks!
