这篇文章将为大家详细讲解有关Dos中怎么获取系统时间，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
代码如下:
rem DOS get current time
rem =======================
rem get yyyy/mm/dd
set mydate=%DATE:~0,10%
echo %mydate%
rem =======================
rem get yyyy
set yyyy=%DATE:~0,4%
echo %yyyy%
rem =======================
rem get mm
set mm=%DATE:~5,2%
echo %mm%
rem =======================
rem get dd
set dd=%DATE:~8,2%
echo %dd%
rem =======================
rem get yyyy-mm-dd
set curdate=%yyyy%-%mm%-%dd%
echo %curdate%
其实bat中获取时间就是利用截取日期字符串的方法
DOS下有字符处理的方法的，总结如下：
在这个日期格式下：”2013-07-22 星期一”， 这个%DATE:~0,10%得到的是2013-07-22
说明：DATE为系统变量，“:”表示开始处理前面的字符串“~0,10”表示从第0个字符开始取10个字符。
输出：
C:\Documents and Settings\Administrator>rem DOS get current time
C:\Documents and Settings\Administrator>rem =======================
C:\Documents and Settings\Administrator>rem get yyyy/mm/dd
C:\Documents and Settings\Administrator>set mydate=2013-07-22
C:\Documents and Settings\Administrator>echo 2013-07-22
2013-07-22
C:\Documents and Settings\Administrator>rem =======================
C:\Documents and Settings\Administrator>rem get yyyy
C:\Documents and Settings\Administrator>set yyyy=2013
C:\Documents and Settings\Administrator>echo 2013
2013
C:\Documents and Settings\Administrator>rem =======================
C:\Documents and Settings\Administrator>rem get mm
C:\Documents and Settings\Administrator>set mm=07
C:\Documents and Settings\Administrator>echo 07
07
C:\Documents and Settings\Administrator>rem =======================
C:\Documents and Settings\Administrator>rem get dd
C:\Documents and Settings\Administrator>set dd=22
C:\Documents and Settings\Administrator>echo 22
22
C:\Documents and Settings\Administrator>rem =======================
C:\Documents and Settings\Administrator>rem get yyyy-mm-dd
C:\Documents and Settings\Administrator>set curdate=2013 -07 -22
C:\Documents and Settings\Administrator>echo 2013 -07 -22
2013 -07 -22
C:\Documents and Settings\Administrator>
