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

FOR /f %%a IN ('WMIC OS GET LocalDateTime ^| FIND "."') DO SET DTS=%%a
SET DATETIME=%DTS:~0,8%-%DTS:~8,6%
第一行输出的格式与时区无关: 20150515150941.077000 + 120 这样，您只需按照自己的愿望格式化输出即可。

也许是这样的:
@call:DateTime
@for %%? in (
"Year :Y"
"Month :M"
"Day :D"
"Hour :H"
"Minutes:I"

这个bat文件(保存为datetimestr.bat)生成3次datetime字符串:(1)长datetime字符串，包含星期几和秒， (2)短的datetime字符串没有它们和 (3)短版代码。
@echo off

为了给予适当的赞扬，我将彼得·莫滕森(Peter Mortensen)(14年6月18日21:02)和欧佩罗(opello)(8月25日至11日14:27)的概念融合在一起。
您可以写得更短，但是这个长版本使阅读和理解代码变得更容易。
