12128	get_calendar misaligns 1st line of WP_Widget_Calendar due to incorrect default timezone	Tim Melanchuk		"on single post pages and calendar archive pages, when get_calendar() is called,
$unixmonth gets set to a time based on UTC by mktime() on line ~1008 of general_template.php. this value is used to determine the padding for the calendar
on line ~1120.

however, by the time mktime() is called to determine whether a new table row is
required for the calendar at line ~1140, the default timezone is correctly set.

the result is that for me (on PST) the 1st day of the calendar always starts one day early 
and the row has an empty day at the end.

my guess is that the timezone filter:
add_filter( 'pre_option_gmt_offset','wp_timezone_override_offset' );

is not occurring soon enough in these circumstances for the widget to display properly.
the widget does display properly on the home page, or category archives. 

on my system, removing the recent change to set the default timezone to UTC at the
beginning of wp_settings.php fixes the problem.
