php設(shè)置:
date_default_timezone_set("UTC");
Yii設(shè)置:
config/main.php 中添加 :'timeZone'=>'UTC',
如此設(shè)置后,php生成的時(shí)間基本都是UTC時(shí)間了.例如:
//輸出當(dāng)前UTC時(shí)間
date("Y-m-d H:i:s");
2.數(shù)據(jù)庫(kù)中存儲(chǔ)UTC時(shí)間.
可以用php控制,也可以通過(guò)設(shè)置數(shù)據(jù)庫(kù)時(shí)區(qū)來(lái)實(shí)現(xiàn).
3.服務(wù)端發(fā)送到前端的時(shí)間均為UTC時(shí)間格式, 由JS將其轉(zhuǎn)換為本地時(shí)間后進(jìn)行顯示.JS內(nèi)部數(shù)據(jù)與顯示數(shù)據(jù)分離.
JS轉(zhuǎn)換函數(shù)參考:
復(fù)制代碼 代碼如下:
/**
* 將UTC時(shí)間轉(zhuǎn)為本地時(shí)間
* @param string utcTime utc時(shí)間字符串 格式 :'Y-m-d H:i:s'
* @return string 本地時(shí)間字符串 格式 :'Y-m-d H:i:s'
*/
function utcToLocal(utcTime) {
if(utcTime==='0000-00-00 00:00:00' || utcTime===null || utcTime==='' || utcTime===undefined)
return utcTime;
var locTime = new Date(); //local時(shí)間對(duì)象
utcTime=utcTime.replace("-", "/").replace("-", "/"); //火狐不兼容'-'分隔日期
//解析字符串及本地時(shí)間賦值
locTime.setTime(Date.parse(utcTime)-locTime.getTimezoneOffset()*60000);
//本地時(shí)間字符串格式化
var year = locTime.getFullYear();
var month = preZero(locTime.getMonth()+1);
var date = preZero(locTime.getDate());
var hour = preZero(locTime.getHours());
var minute = preZero(locTime.getMinutes());
var second = preZero(locTime.getSeconds());
return year+'-'+month+'-'+date+' '+hour+':'+minute+':'+second;
}
/**

* @param string locTime utc時(shí)間字符串 格式 :'Y-m-d H:i:s'
* @return string 本地時(shí)間字符串 格式 :'Y-m-d H:i:s'

php技術(shù)：PHP跨時(shí)區(qū)(UTC時(shí)間)應(yīng)用解決方案，轉(zhuǎn)載需保留來(lái)源！
