在Windows (Windows XP)批处理脚本中，我需要格式化当前日期和时间，以便以后在文件名等中使用。
这类似于堆栈溢出问题如何在批处理文件中添加日期，但也包含时间。
到目前为止，我有这个:
echo %DATE%
echo %TIME%
set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
echo %datetimef%
这使:
28/07/2009
8:35:31.01
2009_07_28__ 8_36_01
是否有一种方法可以允许%TIME%中的个位数小时，以便我可以得到以下结果?
2009_07_28__08_36_01

REM Assumes UK style date format for date environment variable (DD/MM/YYYY).
REM Assumes times before 10:00:00 (10am) displayed padded with a space instead of a zero.
REM If first character of time is a space (less than 1) then set DATETIME to:
REM YYYY-MM-DD-0h-mm-ss
REM Otherwise, set DATETIME to:
REM YYYY-MM-DD-HH-mm-ss
REM Year, month, day format provides better filename sorting (otherwise, days grouped
REM together when sorted alphabetically).
IF "%time:~0,1%" LSS "1" (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-0%time:~1,1%-%time:~3,2%-%time:~6,2%
) ELSE (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-%time:~0,2%-%time:~3,2%-%time:~6,2%
)
ECHO %DATETIME%

这个脚本使用一个WMI接口，主要通过WMIC工具访问，这是Windows的一个组成部分，因为Windows XP专业版(家庭版也支持，但默认情况下不安装该工具)。该脚本还通过创建和调用WSH vbscript来访问WMI接口，并以与WMIC工具提供的相同格式写入控制台输出时间，从而实现了缺少WMIC工具的解决方案。

用斜杠分隔date命令的结果，然后可以将每个标记移动到适当的变量中。
FOR /F "tokens=1-3 delims=/" %%a IN ("%date:~4%") DO (
SET _Month=%%a
SET _Day=%%b
SET _Year=%%c
)
ECHO Month %_Month%
ECHO Day %_Day%
ECHO Year %_Year%
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。
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
还有另一种简单的方法:
set HH=%time:~0,2%
if %HH% LEQ 9 (
set HH=%time:~1,1%
)
