这是我对adatetime字符串的2美分。在MM DD YYYY系统上切换第一个和第二个%DATE:~条目。

    REM ====================================================================================
    REM CREATE UNIQUE DATETIME STRING FOR ADDING TO FILENAME
    REM ====================================================================================
    REM Can handle dd DDxMMxYYYY and DDxMMxYYYY > CREATES YYYYMMDDHHMMSS (x= any character)
    REM ====================================================================================
    REM CHECK for SHORTDATE dd DDxMMxYYYY 
    IF "%DATE:~0,1%" GTR "3" (
        SET DATETIME=%DATE:~9,4%%DATE:~6,2%%DATE:~3,2%%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%
    ) ELSE (
    REM ASSUMES SHORTDATE DDxMMxYYYY
        SET DATETIME=%DATE:~6,4%%DATE:~3,2%%DATE:~0,2%%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%
        )
    REM CORRECT FOR HOURS BELOW 10
    IF %DATETIME:~8,2% LSS 10 SET DATETIME=%DATETIME:~0,8%0%DATETIME:~9,5%
    ECHO %DATETIME%

我今天遇到了这个问题，并解决了它:

SET LOGTIME=%TIME: =0%

它用0代替空格，基本上是零垫小时。

经过一些快速搜索，我没有发现它是否需要命令扩展(仍然使用SETLOCAL DISABLEEXTENSIONS)。

我是这样做的:

REM Generate FileName from date and time in format YYYYMMTTHHMM

Time /T > Time.dat
set /P ftime= < Time.dat

set FileName=LogFile%date:~6%%date:~3,2%%date:~0,2%%ftime:~0,2%%ftime:~3,2%.log

echo %FileName%

LogFile201310170928.log

为了生成一个YYYY-MM-DD hh:mm:ss(24小时)时间戳，我使用:

SET CURRENTTIME=%TIME%
IF "%CURRENTTIME:~0,1%"==" " (SET CURRENTTIME=0%CURRENTTIME:~1%)
FOR /F "tokens=2-4 delims=/ " %%A IN ('DATE /T') DO (SET TIMESTAMP=%%C-%%A-%%B %CURRENTTIME%)

这个bat文件(保存为datetimestr.bat)生成3次datetime字符串:(1)长datetime字符串，包含星期几和秒， (2)短的datetime字符串没有它们和 (3)短版代码。

@echo off
REM "%date: =0%" replaces spaces with zeros
set d=%date: =0%
REM "set yyyy=%d:~-4%" pulls the last 4 characters
set yyyy=%d:~-4%
set mm=%d:~4,2%
set dd=%d:~7,2%
set dow=%d:~0,3%
set d=%yyyy%-%mm%-%dd%_%dow%

set t=%TIME: =0%
REM "%t::=%" removes semi-colons
REM Instead of above, you could use "%t::=-%" to 
REM replace semi-colons with hyphens (or any 
REM non-special character)
set t=%t::=%
set t=%t:.=%

set datetimestr=%d%_%t%
@echo  Long date time str = %datetimestr%

set d=%d:~0,10%
set t=%t:~0,4%
set datetimestr=%d%_%t%
@echo Short date time str = %datetimestr%


@REM Short version of the code above
set d=%date: =0%
set t=%TIME: =0%
set datetimestr=%d:~-4%-%d:~4,2%-%d:~7,2%_%d:~0,3%_%t:~0,2%%t:~3,2%%t:~6,2%%t:~9,2%
@echo Datetimestr = %datetimestr%

为了给予适当的赞扬，我将彼得·莫滕森(Peter Mortensen)(14年6月18日21:02)和欧佩罗(opello)(8月25日至11日14:27)的概念融合在一起。

您可以写得更短，但是这个长版本使阅读和理解代码变得更容易。
