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

也许是这样的:
@call:DateTime
@for %%? in (
"Year :Y"
"Month :M"
"Day :D"
"Hour :H"
"Minutes:I"
"Seconds:S"
) do @for /f "tokens=1-2 delims=:" %%# in (%%?) do @for /f "delims=" %%_ in ('echo %%_DT_%%$_%%') do @echo %%# : _DT_%%$_ : %%_
:: OUTPUT
:: Year : _DT_Y_ : 2014
:: Month : _DT_M_ : 12
:: Day : _DT_D_ : 17
:: Hour : _DT_H_ : 09
:: Minutes : _DT_I_ : 04
:: Seconds : _DT_S_ : 35

为了在文件名中使用数字日期的一个非常简单的解决方案，请使用以下代码:
set month=%date:~4,2%
set day=%date:~7,2%
set curTimestamp=%month%%day%%year%
rem then the you can add a prefix and a file extension easily like this
echo updates%curTimestamp%.txt
设置xtime = % % 如果“%xtime:~0,1%”==“”则设置xtime=0%xtime:~1,7% 设置isodate = %日期:~ -4% %日期:~ 3,2% %日期:~ 0,2% _ % xtime: ~ 0, 2% % xtime: ~ 3, 2% %时间:~ 6 2%
for /f "tokens=1-4 delims=/ " %%I in ("%DATE%") do set curdate=%%K_%%J_%%I
for /f "tokens=1-4 delims=:," %%I in ("%TIME: =0%") do set curtime=%%I_%%J_%%K
echo %curdate%__%curtime%
如果您的系统使用另一个替换delims符号(用于切片到%%I，%%J…) 如果您的系统使用另一个D/M/Y订单，也可以编辑curdate
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。
