查看ZIP文件中的“Date.exe”，并将其重命名为“DateFormat.exe”(以避免冲突)。

把它放在你的Windows system32文件夹中。

它有很多“日期输出”选项。

如需帮助，请使用DateFormat.exe——h

我不确定如何将其输出放入环境变量中…使用设置。

不幸的是，这并不是不受区域设置的影响，但它确实是你想要的。

set hour=%time:~0,2%
if "%time:~0,1%"==" " set hour=0%time:~1,1%
set _my_datetime=%date:~10,4%-%date:~4,2%-%date:~7,2%_%hour%%time:~3,2%

你能在维基百科上找到的东西真是太神奇了。

给定一个已知位置，供函数形式参考。ECHOTIMESTAMP调用显示了如何将时间戳转换为变量(本例中为DTS)。

@ECHO off

CALL :ECHOTIMESTAMP
GOTO END

:TIMESTAMP
SETLOCAL  EnableDelayedExpansion
    SET DATESTAMP=!DATE:~10,4!-!DATE:~4,2!-!DATE:~7,2!
    SET TIMESTAMP=!TIME:~0,2!-!TIME:~3,2!-!TIME:~6,2!
    SET DTS=!DATESTAMP: =0!-!TIMESTAMP: =0!
ENDLOCAL & SET "%~1=%DTS%"
GOTO :EOF

:ECHOTIMESTAMP
SETLOCAL
    CALL :TIMESTAMP DTS
    ECHO %DTS%
ENDLOCAL
GOTO :EOF

:END

EXIT /b 0

并保存到文件，timestamp.bat，下面是输出:

将Powershell合并到一个批处理文件中，并使用元变量来分配每个:

@echo off
for /f "tokens=1-6 delims=-" %%a in ('PowerShell -Command "& {Get-Date -format "yyyy-MM-dd-HH-mm-ss"}"') do (
    echo year: %%a
    echo month: %%b
    echo day: %%c
    echo hour: %%d
    echo minute: %%e
    echo second: %%f
)

如果您更喜欢月份名称MMM或MMMM以及12小时到24小时格式hh或hh，您也可以更改格式

在Windows 7中，这段代码适用于我:

SET DATE=%date%
SET YEAR=%DATE:~0,4%
SET MONTH=%DATE:~5,2%
SET DAY=%DATE:~8,2%
ECHO %YEAR%
ECHO %MONTH%
ECHO %DAY%

SET DATE_FRM=%YEAR%-%MONTH%-%DAY% 
ECHO %DATE_FRM%
