用PHP

$start = strtotime('20140227050000');
$end = strtotime('20140227230000');
$step = strtotime('1970-01-01 08:30:00');
$data = array();
while (($start+=$step) <= $end) {
    $data[] = array(
        's'=>date('Y-m-d H:i:s',($start-strtotime('1970-01-01 08:15:00'))),
        'e'=>date('Y-m-d H:i:s',$start)
    );
}
echo '<pre>';
var_dump($data);

將data資料插入sql表即可

再來個MYSQL的

-- 删除原有表
DROP TABLE IF EXISTS `t`;
-- 创建数据表
CREATE TABLE IF NOT EXISTS `t` (
    `s` varchar(255),
    `e` varchar(255)
);
-- 创建存储
create procedure protest()
begin
declare s int;
declare t int;
declare e int;
set s=UNIX_TIMESTAMP('20140227050000');
set t=900;
set e=UNIX_TIMESTAMP('20140227230000');
while s<e do
        set s=s+t;
    insert into t(`s`,`e`) values(FROM_UNIXTIME(s),FROM_UNIXTIME(s+t));
       set s=s+t;
end while;
end;
-- 调用存储
call protest();
-- 删除存储
drop procedure protest;

你是要產生這樣的表結構？還是說這張表已經存在了想要插入這樣的表格內容
