这个是在XP下能通过,但是WIN2000下就不行了,请高手指点该如何修改

直接调用VBS里面的date()-1可以吗？

恩,可以,只要能实现就行

参考一个 不知道2000下怎么样
@echo off
set p1=%date:~0,4%
set p2=%date:~5,2%
set p3=%date:~8,2%
setlocal enabledelayedexpansion
for /l %%a in (1,1,3) do (
for /f "delims=0 tokens=*" %%i in ("!p%%a!") do set p%%a=%%i
)
SET TT=1
if %p3% gtr %TT% goto ppp
:nxt
set/a p2-=1
if %p2% equ 0 set/a p1-=1&&set p2=12
set/a PN2="^!(p1%%4) & ^!(^!(p1%%100)) | ^!(p1%%400)",PN2=28+PN2
for /f "tokens=%p2%" %%i in ("31 %pN2% 31 30 31 30 31 31 30 31 30 31") do set/a p3=%p3%+%%i
if %p3% leq %tt% goto nxt
:ppp
set/a p3=%p3%-%tt%
set p2=0%p2%
set p2=%p2:~-2,2%
set p3=0%p3%
set p3=%p3:~-2,2%
echo %p1%-%p2%-%p3%
pause

VBS计算当前日期加减日期

@echo off
::::备份系统原时间日期格式
regedit /e "%temp%\bak.reg" "HKEY_CURRENT_USER\Control Panel\International"
::::统一格式化系统日期格式
>aDate.reg echo REGEDIT4
>>aDate.reg echo.
>>aDate.reg echo
>>aDate.reg echo "sShortDate"="yyyy-MM-dd"
>>aDate.reg echo "sDate"="-"
>>aDate.reg echo "sTimeFormat"="HH:mm:ss"
regedit /s aDate.reg&del aDate.reg

:::用VBS计算当前日期减 20 天，如果要当前之后的 20 天请将 ↓下面的 -20 改成 +20
>tmp.vbs echo Wscript.echo FormatDateTime (DateAdd("d", -20 ,Date),2)
for /f "delims=" %%i in ('cscript.exe //nologo tmp.vbs') do set aDate=%%i&del tmp.vbs

echo 20天前是 %aDate%
::::这里你批处理的开始

::::还原系统原时间日期格式
regedit /s "%temp%\bak.reg"&del "%temp%\bak.reg"
pause

>tmp.vbs echo Wscript.echo FormatDateTime (DateAdd("d", -20 ,Date),2) for /f "delims=" %%i in ('cscript.exe //nologo tmp.vbs') do set aDate=%%i&del tmp.vbs简化这样就可以了,但是兼容性不强,而6楼不存在BUG

谢谢各位,问题已经解决!
