【日期時間】批處理標準化擷取當前系統日期

作業系統不同，日期格式也可能不同：

星期二 2008-07-29
2008-07-29 星期二
07/29/2008 Tue
Tue 07/29/2008

 

再考慮到中、英之外的其它語言的作業系統，日期格式的種類實在太多了。
要想標準化地擷取當前系統日期2008-07-28，直接截取%date%變數的方法是不行的。

 

【方案一】BAT + REG

 

@echo off<br />rem 無法保證在中、英之外的其它語言的作業系統上得到正確結果<br />for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (<br /> set "RegDateOld=%%a"<br />)<br />set RegDateOld=%RegDateOld:~-8%<br />reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul<br />set Today=%date: =%<br />reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul<br />set "Week=Mon Tue Wed Thu Fri Sat Sun 星期一 星期二 星期三 星期四 星期五 星期六 星期日"<br />for %%a in (%Week%) do (<br /> call set "Today=%%Today:%%a=%%"<br />)<br />echo,%Today%<br />pause

 

【方案二】BAT + REG

 

@echo off<br />for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (<br /> set "RegDateOld=%%a"<br />)<br />set RegDateOld=%RegDateOld:~-8%<br />reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul<br />set Today=%date: =%<br />reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul<br />if "%Today:~0,1%" gtr "9" (<br /> set Today=%Today:~-10%<br />) else (<br /> set Today=%Today:~0,10%<br />)<br />echo,%Today%<br />pause

 

【方案三】BAT + REG

 

@echo off<br />for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (<br /> set "RegDateOld=%%a"<br />)<br />set RegDateOld=%RegDateOld:~-8%<br />reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul<br />type nul>"%temp%/MyFile.tmp"<br />for /f %%a in ('dir "%temp%/MyFile.tmp" ^| findstr /i "MyFile.tmp"') do (<br /> set Today=%%a<br />)<br />reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul<br />echo,%Today%<br />pause

 

【方案四】BAT + WMIC

 

 @echo off<br />for /f "tokens=2 delims==" %%a in ('wmic path win32_operatingsystem get LocalDateTime /value') do (<br /> set t=%%a<br />)<br />set Today=%t:~0,4%-%t:~4,2%-%t:~6,2%<br />echo,%Today%<br />pause

 

【方案五】BAT + VBS

 

 @echo off<br />>"%temp%/DateCalculate.vbs" echo dt=date()<br />>>"%temp%/DateCalculate.vbs" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)<br />>>"%temp%/DateCalculate.vbs" echo wscript.echo s<br />for /f %%a in ('cscript /nologo "%temp%/DateCalculate.vbs"') do set (<br /> Today=%%a<br />)<br />echo,%Today%<br />pause

 

【方案六】BAT + REGEDIT

 

@echo off<br />rem 需要保證登錄編輯程式沒有處於鎖定狀態<br />regedit /e "%temp%/bak.reg" "HKEY_CURRENT_USER/Control Panel/International"<br />>"%temp%/new.reg" echo REGEDIT4<br />>>"%temp%/new.reg" echo,<br />>>"%temp%/new.reg" echo [HKEY_CURRENT_USER/Control Panel/International]<br />>>"%temp%/new.reg" echo "sShortDate"="yyyy-MM-dd"<br />regedit /s "%temp%/new.reg"<br />set Today=%date: =%<br />regedit /s "%temp%/bak.reg"<br />if "%Today:~0,1%" gtr "9" (<br /> set Today=%Today:~-10%<br />) else (<br /> set Today=%Today:~0,10%<br />)<br />echo,%Today%<br />pause

 

【方案七】BAT + DEBUG

 

@echo off<br />for /f "tokens=6,8 delims== " %%a in ('^(echo a100^&echo mov ah^,2a^&echo int 21^&echo.^&echo p 2^&echo q^)^|debug^|find "CX"') do (<br /> set /a y=0x%%a<br /> set md=%%b<br />)<br />set /a m=0x%md:~,2%<br />set /a d=0x%md:~-2%<br />set m=0%m%<br />set d=0%d%<br />set Today=%y%-%m:~-2%-%d:~-2%<br />echo,%Today%<br />pause
