操作系统不同,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
再考虑到中、英之外的其它语言的操作系统,日期格式的种类实在太多了。要想标准化地获取当前系统日期20080728,以下两个方法都不好:
1. 直接使用系统变量 %date% 进行字符串截取
2. 直接对 date 命令的结果进行字符串截取
实际上日期格式是由注册表 HKEY_CURRENT_USER\Control Panel\International 里面 sShortDate 的值来决定的。
推荐使用其它方法来获取系统日期:
【方案1】BAT + PowerShell- @echo off
- REM Win7/Win10/Win11等系统自带PowerShell
- for /f %%i in ('powershell -c "Get-Date -uformat '%%Y%%m%%d'"') do (
- set "Today=%%i"
- )
- echo,%Today%
- pause
-
- for /f "delims=" %%i in ('powershell -c "Get-Date -UFormat '%%Y-%%m-%%d %%H:%%M:%%S'"') do (
- set "SysTS=%%i"
- )
- echo %SysTS%
- pause
复制代码 【方案2】BAT + WMIC- @echo off
- for /f "tokens=2 delims==" %%i in ('wmic path win32_operatingsystem get LocalDateTime /value ^| findstr "="') do (
- set "strDate=%%i"
- )
- set "Today=%strDate:~0,4%%strDate:~4,2%%strDate:~6,2%"
- echo,%Today%
- pause
-
- set "Now=%strDate:~0,4%-%strDate:~4,2%-%strDate:~6,2% %strDate:~8,2%:%strDate:~10,2%:%strDate:~12,2%"
- echo %Now%
- pause
复制代码 【方案3】BAT + mshta- @echo off
- for /f %%i in ('mshta "vbscript:CreateObject("Scripting.FileSystemObject").GetStandardStream(1).WriteLine(Right(Year(Now),4)&Right("0"&Month(Now),2)&Right("0"&Day(Now),2))(Window.Close)"') do (
- set "Today=%%i"
- )
- echo,%Today%
- pause
复制代码 【方案4】BAT + VBS- @echo off
- >"%temp%\DateCalculate.vbs" echo dt=date()
- >>"%temp%\DateCalculate.vbs" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)
- >>"%temp%\DateCalculate.vbs" echo wscript.echo s
- for /f %%a in ('cscript /nologo "%temp%\DateCalculate.vbs"') do (
- set Today=%%a
- )
- echo,%Today%
- pause
复制代码 【方案5】BAT + REG- @echo off
- REM 无法保证在中、英之外的其它语言的操作系统上得到正确结果
- for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate') do (

- for %%a in (%Week%) do (
- call set "Today=%%Today:%%a=%%"
- )
- echo,%Today%
- pause
复制代码 【方案6】BAT + REG- @echo off
- for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate') do (
- set "RegDateOld=%%a"
- )
- set RegDateOld=%RegDateOld:~-8%
- reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul
- set Today=%date: =%

- if "%Today:~0,1%" gtr "9" (
- set Today=%Today:~-10%
- ) else (
- set Today=%Today:~0,10%
- )
- echo,%Today%
- pause
复制代码 【方案7】BAT + REG- @echo off
- for /f "delims=" %%a in ('reg query "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate') do (
- set "RegDateOld=%%a"
- )
- set RegDateOld=%RegDateOld:~-8%
- reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul
- type nul>"%temp%\MyFile.tmp"
- for /f %%a in ('dir "%temp%\MyFile.tmp" ^| findstr /i "MyFile.tmp"') do (
- set Today=%%a
- )
- reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul
- echo,%Today%
- pause
复制代码 【方案8】BAT + REGEDIT- @echo off
- REM 需要保证注册表编辑器没有处于锁定状态
- regedit /e "%temp%\bak.reg" "HKEY_CURRENT_USER\Control Panel\International"
- >"%temp%\new.reg" echo REGEDIT4
- >>"%temp%\new.reg" echo,
- >>"%temp%\new.reg" echo [HKEY_CURRENT_USER\Control Panel\International]
- >>"%temp%\new.reg" echo "sShortDate"="yyyy-MM-dd"
- regedit /s "%temp%\new.reg"

- regedit /s "%temp%\bak.reg"
- if "%Today:~0,1%" gtr "9" (
- set Today=%Today:~-10%
- ) else (
- set Today=%Today:~0,10%
- )
- echo,%Today%
- pause
复制代码 【方案9】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 (
