qwe1234567斑竹,运用出现了一个问题,当时间从00:00到09:59时就会出现错误,无法得到任何结果,其余时间段正常...主管跟我说可能是第一个0上出现了问题,请问大概有解决的方法吗...

各位知道的朋友也请讲解下..

:\Documents and Settings\Administrator>date
The current date is: 10/16/2006 Mon
Enter the new date: (mm-dd-yy)

C:\Documents and Settings\Administrator>time
The current time is: 15:56:45.35
Enter the new time:


set a=%date:~10,4%%date:~4,2%%date:~7,2%@%time:~0,2%%time:~3,2%%time:~6,2%
copy c:\test.bat test%a%.bat

%time%方式在00:00到09:59时没有前面的0
利用延迟变量：

setlocal EnableDelayedExpansion
set time$=%time:~0,8%&&set time$=!time$::=!&&set time$=!time$: =0!
set a=%date:~10,4%%date:~4,2%%date:~7,2%@%time$%
copy c:\test.bat test%a%.bat

不用延迟变量：
set time$=%time:~0,8%
set time$=%time$::=%
set time$=%time$: =0%
set a=%date:~10,4%%date:~4,2%%date:~7,2%@%time$%
copy c:\test.bat test%a%.bat

zxcv:万分感谢,用了第二个的不用延迟变量成功了...

原理：
set time$=%time:~0,8%
获取%time%（“ 9:59:45.35”）前8位，“ 9:59:45”（前第一位小于10时为空格）
set time$=%time$::=%
去处“ 9:59:45”中的“:”冒号：“ 95945”
set time$=%time$: =0%
将“ 95945”中的空格替换为“0”，“095945”
