:: 设置变量，使用变量时需要用一对%包起来
set ORIGINAL_DATE=%date%
echo %ORIGINAL_DATE%
@echo =========日期按照YYYY-MM-DD格式显示======================
:: 日期截取遵从格式 %date:~x,y%，表示从第x位开始，截取y个长度(x,y的起始值为0)
:: windows下DOS窗口date的结果 2016/09/03 周六
:: 年份从第0位开始截取4位，月份从第5位开始截取2位，日期从第8位开始截取2位

:: 当时钟小于等于9时,前面有个空格，这时我们少截取一位，从第1位开始截取
set TMP_HOUR=%time:~1,1%
set NINE=9
set ZERO=0
:: 处理时钟是个位数的时候前面补上一个0, LEQ表示小于等于
