我正在尝试编写一个批处理脚本,以安全的方式获取当前日期,月份和年份(即独立于日期格式)。不幸的是,我发现的所有互联网资源都提出了类似的内容:
SET CURRENT_DATE=%DATE: =0%
SET YEAR=%DATE:~-4%
SET MONTH=%DATE:~3,2%
SET DAY=%DATE:~5,2%
如果我的日期格式为yyyy / mm / dd或yyyy-mm-dd,但如果格式为yy-mm-dd或其他格式,则无效。有没有一种安全的方式来获得年,月和日?
还有一个问题 - 是否可以知道日期分隔符是什么(第一种情况为/
,其他情况为-
。

此代码的前四行将为您提供XP Pro及更高版本中可靠的YY DD MM YYYY HH Min Sec变量。
@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"
set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"
pause
以下是VBS解决方案:
:: date time using WSH/VBS
:: datetime.bat V4.2

:: This uses Windows Scripting Host to set variables to

首先,您可以从注册表(某处)检索当前设置 格式以及分隔符。
但是使用wmic
更容易,它总是采用相同的格式,唯一的缺点是,每次启动它都需要一些时间。
@echo off
setlocal EnableDelayedExpansion
FOR /F "skip=1 tokens=1-6" %%A IN ('WMIC Path Win32_LocalTime Get Day^,Hour^,Minute^,Month^,Second^,Year /Format:table') DO (
if "%%B" NEQ "" (
SET /A FDATE=%%F*10000+%%D*100+%%A
SET /A FTIME=%%B*10000+%%C*100+%%E
)
)
ECHO !FDATE! - !FTIME!

提取日,月和年(与语言区无关)
我不会使用WMIC,因为它资源非常高,需要一段时间才能完成,尤其是在较慢的计算机上。以下脚本使用户'来自注册表的本地化,这是与语言环境无关的。据我所知,是唯一有效的批量解决方案。当然你也可以使用VBScript调用,但对我来说这是一个偏离主题的内容。
@echo off
::: Begin set date
setlocal EnableExtensions EnableDelayedExpansion
:: Determine short date format (independent from localization) from registry
for /f "skip=1 tokens=3-5 delims=- " %%L in ( '2^>nul reg query "HKCU\Control Panel\International" /v "sShortDate"' ) do (
:: Since we can have multiple (short) date formats we only use the first char from the format in a new variable
set "_L=%%L" && set "_L=!_L:~0,1!" && set "_M=%%M" && set "_M=!_M:~0,1!" && set "_N=%%N" && set "_N=!_N:~0,1!"
:: Now assign the date values to the new vars
for /f "tokens=2-4 delims=/-. " %%D in ( "%date%" ) do ( set "!_L!=%%D" && set "!_M!=%%E" && set "!_N!=%%F" )
)
:: Print the values as is
echo.
echo This is the original date string --^> %date%
echo These are the splitted values --^> Day: %d%, Month:%m%, Year: %y%.
echo.
endlocal
仅提取年份
对于我写的脚本,我只想提取年份(与语言环境无关),所以我想出了这个oneliner,因为我无法找到任何解决方案。它使用' DATE' var,多个分隔符并检查大于31的数字。然后将是当前年份。与其他一些解决方案相比,它的资源较少。
@echo off
setlocal EnableExtensions
for /f " tokens=2-4 delims=-./ " %%D in ( "%date%" ) do ( if %%D gtr 31 ( set "_YEAR=%%D" ) else ( if %%E gtr 31 ( set "_YEAR=%%E" ) else ( if %%F gtr 31 ( set "_YEAR=%%F" ) ) ) )
echo And the year is... %_YEAR%.
echo.
endlocal
