cd F:mysql-5.7.21-winx64in
mysql -u root -p
輸入密碼即可登陸MySQL
select now(); 查看mysql系統時間。和當前時間做對比
set global time_zone = '+8:00'; 設置時區更改為東八區

	You must configure either the server or JDBC driver
	(via the serverTimezone configuration property)
	to use a more specifc time zone value
	if you want to utilize time zone support.
