cmd命令中time命令0～9点现实格式问题

@echo off
set abc=%date:~0,10%_%TIME:~0,2%-%TIME:~3,2%-%TIME:~6,2%
md %abc%

bat 按时间创建文件夹，如果是上午创建的文件夹，文件夹就会被分成2个

1个是2010-10-12_ 
1个是7-12-53

10点钟以后创建的就正常了
2010-10-12_21-05-42

解决方法

@echo off
set a=%date:~0,10%_
set b=%TIME:~0,2%
if %TIME:~0,2% leq 9 (set b=0%TIME:~1,1%)else set b=%TIME:~0,2%
set c=-%TIME:~3,2%-%TIME:~6,2%
echo "%a%%b%%c%"
md "%a%%b%%c%"
pause
