dos下獲取系統(tǒng)時間的實現(xiàn)代碼，需要的朋友可以參考下

  
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% 

其實bat中獲取時間就是利用截取日期字符串的方法

DOS下有字符處理的方法的，總結(jié)如下：

在這個日期格式下：”2013-07-22 星期一”，這個%DATE:~0,10%得到的是2013-07-22
說明：DATE為系統(tǒng)變量，“:”表示開始處理前面的字符串“~0,10”表示從第0個字符開始取10個字符。

輸出：

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
