时间操作、时间戳

//获取当前时间：
var myDate = new Date();//当前时间
var year = myDate.getFullYear();//当前年份
var month = myDate.getMonth() + 1;//当前月份
var day = myDate.getDate();//当前日


var getYear = myDate.getYear(); //获取当前年份(2位)
var getFullYear = myDate.getFullYear(); //获取完整的年份(4位,1970-????)
var getMonth = myDate.getMonth(); //获取当前月份(0-11,0代表1月)
var getDate = myDate.getDate(); //获取当前日(1-31)
var getDay = myDate.getDay(); //获取当前星期X(0-6,0代表星期天)
var getTime = myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)
var getHours = myDate.getHours(); //获取当前小时数(0-23)
var getMinutes = myDate.getMinutes(); //获取当前分钟数(0-59)
var getSeconds = myDate.getSeconds(); //获取当前秒数(0-59)
var getMilliseconds = myDate.getMilliseconds(); //获取当前毫秒数(0-999)
var toLocaleDateString = myDate.toLocaleDateString(); //获取当前日期
var toLocaleTimeString    = myDate.toLocaleTimeString(); //获取当前时间
var toLocaleString = myDate.toLocaleString( ); //获取日期与时间
