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

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 Can handle dd DDxMMxYYYY and DDxMMxYYYY > CREATES YYYYMMDDHHMMSS (x= any character)

如果安装了PowerShell，那么您可以轻松可靠地以任何您想要的格式获取日期/时间，例如:
for /f %%a in ('powershell -Command "Get-Date -format yyyy_MM_dd__HH_mm_ss"') do set datetime=%%a
move "%oldfile%" "backup-%datetime%"
当然，现在总是安装PowerShell，但在Windows XP上，你可能只会想要使用这种技术，如果你的批处理脚本是在一个已知的环境中使用，你知道PS可用(或者检查你的批处理文件，如果PowerShell可用…)
你可能会合理地问:如果你可以使用PowerShell来获取日期/时间，为什么还要使用批处理文件，但我认为一些明显的原因是:(a)你对PowerShell并不熟悉，仍然更喜欢用老式的批处理文件方式来做大多数事情;或者(b)你正在更新一个旧脚本，不想把整个脚本移植到PS上。
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

@echo Long date time str = %datetimestr%
set d=%d:~0,10%

set datetimestr=%d%_%t%
@echo Short date time str = %datetimestr%
@REM Short version of the code above

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。
也许是这样的:

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)。
