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
当前回答
如果你不需要这个格式:
2009_07_28__08_36_01
然后你可以使用以下3行代码，使用%date%和%time%:
set mydate=%date:/=%
set mytime=%time::=%
set mytimestamp=%mydate: =_%_%mytime:.=_%
注意:字符/和:被删除，字符。空格被下划线取代。
示例输出(摄于8/5/15星期三下午12:49，时间为50秒93毫秒):
echo %mytimestamp%
Wed_08052015_124950_93

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%)
@ECHO OFF
: Sets the proper date and time stamp with 24Hr Time for log file naming
: convention ('YYYYMMDD_HHMMSS')
: Scrapes the characters out of their expected permissions in the date/time
: environment variables.
: Expects a date format of '____MM_DD_YYYY'
: Expects a time format of 'HH:MM:SS' or ' H:MM:SS'
SET HOUR=%time:~0,2%
SET dtStamp9=%date:~-4%%date:~4,2%%date:~7,2%_0%time:~1,1%%time:~3,2%%time:~6,2%
SET dtStamp24=%date:~-4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%
if "%HOUR:~0,1%" == " " (SET dtStamp=%dtStamp9%) else (SET dtStamp=%dtStamp24%)
ECHO %dtStamp%

Windows中SET命令支持的offset:length格式将不允许您填充您似乎感兴趣的0。
但是，您可以编写一个BATCH脚本来检查小时是否小于10和 相应地用不同的回声字符串进行填充。
您将在此链接中找到关于SET命令的一些信息。
您还可以更改其他编程方法以达到此目的。
在unix bash (Windows上的Cygwin可用)中，只需说，
date +%Y_%m_%d__%H_%M_%S
它总是正确地填充。
下面是如何生成一个日志文件名(基于http://ss64.com/nt/syntax-getdate.html):)
@ECHO OFF
:: Check WMIC is available
WMIC.EXE Alias /? >NUL 2>&1 || GOTO s_error
:: Use WMIC to retrieve date and time
FOR /F "skip=1 tokens=1-6" %%G IN ('WMIC Path Win32_LocalTime Get Day^,Hour^,Minute^,Month^,Second^,Year /Format:table') DO (
IF "%%~L"=="" goto s_done
Set _yyyy=%%L
Set _mm=00%%J
Set _dd=00%%G
Set _hour=00%%H
SET _minute=00%%I
SET _second=00%%K
)
:s_done
:: Pad digits with leading zeros
Set _mm=%_mm:~-2%
Set _dd=%_dd:~-2%
Set _hour=%_hour:~-2%
Set _minute=%_minute:~-2%
Set _second=%_second:~-2%
Set logtimestamp=%_yyyy%-%_mm%-%_dd%_%_hour%_%_minute%_%_second%
goto make_dump
:s_error
echo WMIC is not available, using default log filename
Set logtimestamp=_
:make_dump
set FILENAME=database_dump_%logtimestamp%.sql
...
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
