本文介绍了一种将日期时间格式转换为时间戳，以及将时间戳转换回日期时间格式的方法。提供了详细的JavaScript函数实现，包括时间戳的获取、时间格式化及时间差计算。


/**
 * 将时间转换成时间戳
 * @param DateTime 为时间格式下的时间 2018/06/14 13:00:00或2018-06-14 13:00:00
 * @returns {number}
 * @constructor
 */
function DateToUnix(DateTime) {
  var oDate =  new Date(Date.parse(DateTime.replace(/-/g, "/")));
  var Unix = oDate.getTime();
    return Unix;
}
function DeCa(Natural) {
    var NaturalNum;
    if (Natural<10){
        NaturalNum = "0"+Natural;
    }else {
        NaturalNum = Natural;
    }
    return NaturalNum;
}
/**
 * 将时间戳转化为时间
 * @param UnixTime 时间 格式 2018/06/14 13:00:00
 * @param ShowTime 时间展示格式 选择 2018/06/14 13:00:00或2018-06-14 13:00:00等等格式
 * @constructor
