Dos中怎么獲取系統(tǒng)時間

這篇文章將為大家詳細講解有關Dos中怎么獲取系統(tǒng)時間，文章內容質量較高，因此小編分享給大家做個參考，希望大家閱讀完這篇文章后對相關知識有一定的了解。

代碼如下:

  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
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>
