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 ====================================================================================
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%
其他回答
我是这样做的:
REM Generate FileName from date and time in format YYYYMMTTHHMM
Time /T > Time.dat
set /P ftime= < Time.dat
set FileName=LogFile%date:~6%%date:~3,2%%date:~0,2%%ftime:~0,2%%ftime:~3,2%.log
echo %FileName%
LogFile201310170928.log
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。

为了生成一个YYYY-MM-DD hh:mm:ss(24小时)时间戳，我使用:
SET CURRENTTIME=%TIME%
IF "%CURRENTTIME:~0,1%"==" " (SET CURRENTTIME=0%CURRENTTIME:~1%)
FOR /F "tokens=2-4 delims=/ " %%A IN ('DATE /T') DO (SET TIMESTAMP=%%C-%%A-%%B %CURRENTTIME%)
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。
