这个批处理脚本将完全按照O.P.的要求执行(在Windows XP SP3上测试)。

我还使用了前面“jph”所描述的聪明的注册表技巧，我认为这是在任何新的或旧的Windows系统上获得100%一致的日期格式“yyyy_MM_dd”的最简单方法。对一个注册表值的更改是瞬时、临时和微不足道的;它只持续几毫秒，然后立即恢复。

双击此批处理文件进行即时演示，命令提示符窗口将弹出并显示您的时间戳. . . . .

Parameters:
%date:~4,2% -- month
%date:~7,2% -- days
%date:~10,4% -- years

%time:~1,1% -- hours
%time:~3,2% -- minutes
%time:~6,2% -- seconds
%time:~9,2% -- mili-seconds

%date:~4,2%%date:~7,2%%date:~10,4% : MMDDYYYY
%date:~7,2%%date:~4,2%%date:~10,4% : DDMMYYYY
%date:~10,4%%date:~4,2%%date:~7,2% : YYYYMMDD

我真的是批处理文件的新手，这是我的代码!!(我不知道为什么，但我不能结合日期/t和时间/t在一起，我不能直接使用%date%和%time%没有变量…)

@ECHO OFF
set ldt=%date% %time%
echo %ldt%>> logs.txt
EXIT

它在某种程度上是从其他人那里重用的(问题是获得一个格式化的时间作为文件名)。

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%)

创建一个名为“search_files.bat”的文件，并将下面的内容放入该文件中。然后双击它。临时的%THH%变量被放置在适当的位置来处理AM。如果时间的前两位数字为0,Windows将忽略LOG文件的其余文件名。

CD .
SET THH=%time:~0,2%
SET THH=%THH: =0%
dir /s /b *.* > %date:~10,4%-%date:~4,2%-%date:~7,2%@%THH%.%time:~3,2%.%time:~6,2%.LOG

我尝试了公认的答案，效果很好。不幸的是，美国时间格式似乎是H:MM:SS.CS，前面缺少0导致上午10点之前的解析问题。为了克服这个障碍，并允许解析大多数世界时间格式，我提出了这个简单的例程，它似乎工作得相当好。

:ParseTime
rem The format of %%TIME%% is H:MM:SS.CS or (HH:MM:SS,CS) for example 0:01:23.45 or 23:59:59,99
FOR /F "tokens=1,2,3,4 delims=:.," %%a IN ("%1") DO SET /A "%2=(%%a * 360000) + (%%b * 6000) + (%%c * 100) + %%d"
GOTO :EOF

这个例程的好处是将时间字符串作为第一个参数传入，将希望包含时间(以厘秒为单位)的环境变量名称作为第二个参数传入。例如:

CALL :ParseTime %START_TIME% START_CS
CALL :ParseTime %TIME% END_CS
SET /A DURATION=%END_CS% - %START_CS%
