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
@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%
PAUSE

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
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%
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)。
这个批处理脚本将完全按照O.P.的要求执行(在Windows XP SP3上测试)。
我还使用了前面“jph”所描述的聪明的注册表技巧，我认为这是在任何新的或旧的Windows系统上获得100%一致的日期格式“yyyy_MM_dd”的最简单方法。对一个注册表值的更改是瞬时、临时和微不足道的;它只持续几毫秒，然后立即恢复。
