Thanks for introducing me the sitecustomize.pl. This is new for me to notice! However, could you explain a little for what purpose of this work is supposed to be done ? Though, still can't do the trick I want. what I would expect is : 
$tm = time;
@gmt = gmtime ( $tm ) ;
@local = localtime ( $tm );
# and @gmt should identical to @local

This could happen if I change my system tz to GMT+0
