【JavaScript Date Object】


# #Date object

Date object: used to set and get the current time.

Date object methods are divided into two types:

One uses local time; One uses world time UTC (that is, if there is "UTC" in the method), it means World time; (based on 0 degrees longitude).

Get the current time of the system:

var time = new Date();
console.log(time);
获取具体时间(get)
Copy after login

All get methods have UTC acquisition, except getYear()\getTimes( )

Obtain time other than UTC is world time):
get[UTC]FullYear( )——获取年份;
get[UTC]Month( )——获取月份;
get[UTC]Date( )——获取日期;
get[UTC]Day( )——获取星期;
get[UTC]Hours( )——获取小时;
get[UTC]Minutes( )——获取分钟;
get[UTC]Seconds( )——获取秒数;
get[UTC]Milliseconds( )——获取毫秒;
getTime( ):返回Date对象的内部毫秒,这个值没有“UTC”方法;
getTimezoneOffset():返回当前日期的本地表示与UTC表示之间的时间差的值;
getYear( ):返回Date对象的年份值,建议使用get[UTC]FullYear()。

Three ways to set the time
