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. . . . .

你可以用这些…

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

也许是这样的:

@call:DateTime

@for %%? in (
    "Year   :Y"
    "Month  :M"
    "Day    :D"
    "Hour   :H"
    "Minutes:I"
    "Seconds:S"
) do @for /f "tokens=1-2 delims=:" %%# in (%%?) do @for /f "delims=" %%_ in ('echo %%_DT_%%$_%%') do @echo %%# : _DT_%%$_ : %%_

:: OUTPUT
:: Year    : _DT_Y_ : 2014
:: Month   : _DT_M_ : 12
:: Day     : _DT_D_ : 17

Windows中SET命令支持的offset:length格式将不允许您填充您似乎感兴趣的0。

但是，您可以编写一个BATCH脚本来检查小时是否小于10和 相应地用不同的回声字符串进行填充。

您将在此链接中找到关于SET命令的一些信息。

您还可以更改其他编程方法以达到此目的。

在unix bash (Windows上的Cygwin可用)中，只需说，

date +%Y_%m_%d__%H_%M_%S

它总是正确地填充。

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)。

下面是如何生成一个日志文件名(基于http://ss64.com/nt/syntax-getdate.html):)
