Js中获取时间戳可用var dayMiliseconds = parseInt(new Date().valueOf());Js的时间戳单位为毫秒(1s = 1000 ms),下面是一个将制定的格式转化成UTC时间的函数。
//format the date string from webservice to UTC time; function toUTCtime(dateStr) { //Date(1381243615503+0530),1381243615503,(1381243615503+0800) dateStr += ""; var utcPrefix = 0; var offset = 0; var dateFormatString = "yyyy-MM-dd hh:mm:ss"; var utcTimeString = ""; var totalMiliseconds = 0; var regMatchNums = /d+/gi; var regSign = /[+|-]/gi; var arrNums = dateStr.match(regMatchNums); utcPrefix = parseInt(arrNums[0]); if (arrNums.length > 1) { offset = arrNums[1]; offsetHour = offset.substring(0, 2); offsetMin = offset.substring(2, 4); offset = parseInt(offsetHour) * 60 * 60 * 1000 + parseInt(offsetMin) * 60 * 1000; } if(dateStr.lastIndexOf("+")>-1){ totalMiliseconds= utcPrefix - offset; } else if (dateStr.lastIndexOf("-") > -1) { totalMiliseconds = utcPrefix + offset; } utcTimeString = new Date(totalMiliseconds).format(dateFormatString); return utcTimeString; }
