You would be better off setting the time zone ahead of time:

SET time_zone='UTC';
select FROM_UNIXTIME(1277942400);

SELECT CONVERT_TZ(FROM_UNIXTIME(1277942400), @@session.time_zone,'UTC')

SELECT @@global.time_zone, @@session.time_zone;

time_zone = '+00:00'

date_default_timezone_set("Asia/Shanghai");
