Several ways to obtain the current system date in batch bat standardization

Different operating systems may also have different date formats:

Tuesday 2008-07-29
2008-07-29 Tuesday
07/29/2008 Tue
Tue 07/29/2008

 

Considering operating systems in other languages ​​other than Chinese and English, there are too many types of date formats.
To obtain the current system date 2008-07-28 in a standardized manner, the method of directly intercepting the %date% variable is not possible.

【Program 1】BAT + REG

@echo off
rem There is no guarantee that it is in、Get correct results on operating systems in other languages ​​other than English
for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (
  set "RegDateOld=%%a"

reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul
set Today=%date: =%
reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul
set "Week=Mon Tue Wed Thu Fri Sat Sun Monday Tuesday Wednesday Thursday Friday Saturday Sunday"
for %%a in (%Week%) do (
  call set "Today=%%Today:%%a=%%"
)
echo,%Today%
pause

【Scheme 2】BAT + REG

reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul

【Scheme 3】BAT + REG

  set Today=%%a

【Scheme 4】BAT + WMIC

@echo off

  set t=%%a

【Scheme 5】BAT + VBS

@echo off
>"%temp%/" echo dt=date()
>>"%temp%/" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)

echo,%Today%
pause

【Scheme VI】BAT + REGEDIT

@echo off
rem It is necessary to ensure that the registry editor is not locked
regedit /e "%temp%/" "HKEY_CURRENT_USER/Control Panel/International"
>"%temp%/" echo REGEDIT4
>>"%temp%/" echo,
>>"%temp%/" echo [HKEY_CURRENT_USER/Control Panel/International]

【Scheme 7】BAT + DEBUG

 @echo off
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 (
