Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

Please read the documentation, %G is the ISO year, and if you use it
together with the ISO week modifier (%V) then you'll see that jan 01
falls in the last week of the previous year.

Description:
------------
strftime always displays Jan of year X as Jan of year X-1 when using
'%B, %G' format for some years

Reproduce code:
---------------
function print_time($curr_time)
{
    echo ("Time according to date:\t\t" . date("Y-m-d H:i:s",
$curr_time) . "\n");
    echo ("Time according to strftime:\t" . strftime('%B, %G',
$curr_time) . "\n");
}

$curr_time = strtotime("2006-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("2005-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("2004-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("2003-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("2002-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("2001-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("2000-01-01 00:00:01");print_time ($curr_time);
$curr_time = strtotime("1999-01-01 00:00:01");print_time ($curr_time);

Time according to date:         2006-01-01 00:00:01
Time according to strftime:     January, 2006
