语言	秒	毫秒
JavaScript	Math.round(new Date() / 1000)	new Date().getTime()
Java	System.currentTimeMillis() / 1000	System.currentTimeMillis()
Python	int(time.time())	int(time.time() * 1000)
Go	time.Now().Unix()	time.Now().UnixNano() / 1e6
PHP	time()	(int)(microtime(true) * 1000)
Ruby	Time.now.to_i	(Time.now.to_f * 1000).to_i
C#	DateTimeOffset.UtcNow.ToUnixTimeSeconds()	DateTimeOffset.UtcNow.ToUnixTimeMilliseconds()
Swift	NSDate().timeIntervalSince1970	NSDate().timeIntervalSince1970 * 1000
Objective-C	NSDate date timeIntervalSince1970	NSDate date timeIntervalSince1970 * 1000

JS日期格式化显示 \’yyyy-MM-dd hh:mm:ss\’

const dateFormat = \'yyyy-MM-dd hh:mm:ss\';

Date.prototype.format = function (fmt) {
    let o = {
        "M+": this.getMonth() + 1,
        "d+": this.getDate(),
        "h+": this.getHours(),
        "m+": this.getMinutes(),
        "s+": this.getSeconds(),
        "q+": Math.floor((this.getMonth() + 3) / 3),
        "s": this.getMilliseconds()
    };
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    }
    for (let k in o) {
        if (new RegExp("(" + k + ")").test(fmt)) {
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
        }
    }
    return fmt;
};
