jq日期与时间戳互相转换

方法1：

$.extend({
                myTime: {
                    CurTime: function () {
                        return Date.parse(new Date()) / 1000;
                    },
                    DateToUnix: function (string) {
                        var f = string.split(' ', 2);
                        var d = (f[0] ? f[0] : '').split('-', 3);
                        var t = (f[1] ? f[1] : '').split(':', 3);
                        return (new Date(
                            parseInt(d[0], 10) || null,
                            (parseInt(d[1], 10) || 1) - 1,
                            parseInt(d[2], 10) || null,
                            parseInt(t[0], 10) || null,
                            parseInt(t[1], 10) || null,
                            parseInt(t[2], 10) || null
                        )).getTime() / 1000;
                    },
                    UnixToDate: function (unixTime, isFull, timeZone) {
                        if (typeof (timeZone) == 'number') {
                            unixTime = parseInt(unixTime) + parseInt(timeZone) * 60 * 60;
                        }
                        var time = new Date(unixTime * 1000);
                        var ymdhis = "";
                        ymdhis += time.getUTCFullYear() + "-";
                        ymdhis += (time.getUTCMonth() + 1) + "-";
                        ymdhis += time.getUTCDate();
                        if (isFull === true) {
                            ymdhis += "" + time.getUTCHours() + ":";
                            ymdhis += time.getUTCMinutes() + ":";
                            ymdhis += time.getUTCSeconds();
                        }
                        return ymdhis;
                    }
                }
            });

//将时间转化为时间戳
var noHis = "2017-06-22";
var haveHis = "2017-06-22 00:00:01";
var oNoHis = $.myTime.DateToUnix(noHis); // 1498060800
var ohaveHis = $.myTime.DateToUnix(haveHis); // 1498123193
console.log(oNoHis);
console.log(ohaveHis);
//将时间戳转化为时间对象
var HisBack = "1498060800";
var HaveHisBack = "1498123193";
var oHisBack = $.myTime.UnixToDate(HisBack);
var oHaveHisBack = $.myTime.UnixToDate(HaveHisBack);
console.log(oHisBack);
console.log(oHaveHisBack);

方法2：

// 时间戳转换为日期
            function timestampToTime(timestamp) {
                var date = new Date(timestamp * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000
                Y = date.getFullYear() + '-';
                M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
                D = (date.getDate() < 10 ? '0' + (date.getDate()) : date.getDate()) + ' ';
                h = (date.getHours() < 10 ? '0' + (date.getHours()) : date.getHours()) + ':';
                m = (date.getMinutes() < 10 ? '0' + (date.getMinutes()) : date.getMinutes()) + ':';
                s = (date.getSeconds() < 10 ? '0' + (date.getSeconds()) : date.getSeconds());
                return Y + M + D + h + m + s;
            }
//日期转换为时间戳

　　let timestamp = (new Date(date)).getTime() / 1000;
