帝国CMS自定义列表按时间调用

帝国CMS自定义列表如何按时间调用？
演示代码按8小时、24小时、7天、30天、365天时间调用，大家可以参照代码按实际情况修改3600*72=72小时
8小时内
select count(*) as total from [!db.pre!]ecms_news where unix_timestamp(now())-newstime<3600*720 
select * from [!db.pre!]ecms_news  where unix_timestamp(now())-newstime<3600*720 order by onclick desc
24小时内
select count(*) as total from [!db.pre!]ecms_news where unix_timestamp(now())-newstime<3600*2400
select * from [!db.pre!]ecms_news  where unix_timestamp(now())-newstime<3600*2400 order by onclick desc
7天内
select count(*) as total from [!db.pre!]ecms_news where unix_timestamp(now())-newstime<3600*7*24
select * from [!db.pre!]ecms_news  where unix_timestamp(now())-newstime<3600*7*24 order by onclick desc
一个月
select count(*) as total from [!db.pre!]ecms_news where unix_timestamp(now())-newstime<3600*30*24
select * from [!db.pre!]ecms_news  where unix_timestamp(now())-newstime<3600*30*24 order by onclick desc
一年
select count(*) as total from [!db.pre!]ecms_news where unix_timestamp(now())-newstime<3600*365*24
select * from [!db.pre!]ecms_news  where unix_timestamp(now())-newstime<3600*365*24 order by onclick desc
