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

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)。
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%
如前所述，只有在您知道当前用户使用的格式(例如，MM/dd/yy或dd-MM-yyyy，仅举两个例子)时，解析日期和时间才有用。这是可以确定的，但是当您完成所有的强调和解析时，您仍然会遇到使用了意想不到的格式的情况，需要进行更多的调整。
您还可以使用一些外部程序，它们将以您喜欢的格式返回日期段，但这样做的缺点是需要将实用程序与脚本/批处理一起分发。
也有批处理技巧使用CMOS时钟在一个相当原始的方式，但这是太接近裸线对大多数人来说，也不总是首选的地方来检索日期/时间。
下面是避免上述问题的解决方案。是的，它引入了一些其他问题，但就我的目的而言，我发现这是在现代Windows系统的.bat文件中创建日期戳的最简单、最清晰、最可移植的解决方案。这只是一个示例，但我认为您将看到如何修改其他日期和/或时间格式等。
reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f
reg add "HKCU\Control Panel\International" /v sShortDate /d "yyMMdd" /f
@REM reg query "HKCU\Control Panel\International" /v sShortDate
set LogDate=%date%
reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f
希望这能有所帮助:
set MM=%date:~4,2%
set DD=%date:~7,2%
set YYYY=%date:~10,4%
echo %DD%_%MM%_%YYYY%
这将打印05_06_2021
也许是这样的:
@call:DateTime
@for %%? in (
"Year :Y"
"Month :M"
"Day :D"
"Hour :H"
"Minutes:I"
