篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了php/js将 CST时间转成格式化时间相关的知识，希望对你有一定的参考价值。

PHP :比较简单

$str = ‘Wed Jul 24 11:24:33 CST 2019‘;
echo date(‘Y-m-d H:i:s‘, strtotime($str));
echo date(‘Y-m-d H:i:s‘,strtotime("$date1 -14 hours"));

php 直接格式化的时间相差14个小时，然后我又减去了14个小时，

javascript：好复杂的感觉

dateFormat = function (date, format) 
 
            date = new Date(date);
 
            var o = 
                ‘M+‘ : date.getMonth() + 1, //month
                ‘d+‘ : date.getDate(), //day
                ‘H+‘ : date.getHours(), //hour
                ‘m+‘ : date.getMinutes(), //minute
                ‘s+‘ : date.getSeconds(), //second
                ‘q+‘ : Math.floor((date.getMonth() + 3) / 3), //quarter
                ‘S‘ : date.getMilliseconds() //millisecond
            ;
 
            if (/(y+)/.test(format))
                format = format.replace(RegExp.$1, (date.getFullYear() + ‘‘).substr(4 - RegExp.$1.length));
 
            for (var k in o)
                if (new RegExp(‘(‘ + k + ‘)‘).test(format))
                    format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : (‘00‘ + o[k]).substr((‘‘ + o[k]).length));
 
            return format;
        
 var _xbdate = new Date(dateFormat(‘Wed Jul 24 11:24:33 CST 2019‘,‘yyyy-MM-dd HH:mm:ss‘)); //将CST时间转换为GMT格式

  console.log(_xbdate);

 nowDate = new Date(_xbdate.valueOf() - 60* 60 * 1000*14);// 当前时间减去14小时 

 console.log(nowDate);

var year = nowDate.getFullYear();
var month = nowDate.getMonth() + 1 < 10 ? "0" + (nowDate.getMonth() + 1): nowDate.getMonth() + 1;
var day = nowDate.getDate() < 10 ? "0" + nowDate.getDate() : nowDate.getDate();
var hours = nowDate.getHours()<10?"0" + nowDate.getHours():nowDate.getHours();
var minutes = nowDate.getMinutes()<10?"0" + nowDate.getMinutes():nowDate.getMinutes();
var seconds = nowDate.getSeconds()<10?"0" + nowDate.getSeconds():nowDate.getSeconds();

 var dateStr = year + "-" + month + "-" + day+ " " + hours+ ":" + minutes+ ":" + seconds; //转为YY-mm-dd H:i:s
 console.log(dateStr);
