用户Aacini提出的代码的改进，它具有百分之一秒的分辨率，当时间达到23:59:59,99时不会失败：

for /f "tokens=1,2,3,4 delims=:," %%A in ("%TIME%") do set /a HH=%%A, MM=1%%B-100, SS=1%%C-100, CC=1%%D-100, TBASE=((HH*60+MM)*60+SS)*100+CC

:: Example delay 1 seg.
set /a TFIN=%TBASE%+100

:ESPERAR
for /f "tokens=1,2,3,4 delims=:," %%A in ("%TIME%") do set /a HH=%%A, MM=1%%B-100, SS=1%%C-100, CC=1%%D-100, TACTUAL=((HH*60+MM)*60+SS)*100+CC

if %TACTUAL% lss %TBASE% set /a TACTUAL=%TBASE%+%TACTUAL%
if %TACTUAL% lss %TFIN% goto ESPERAR

如果你有选择或ping，这是可行的。

@echo off
echo.
if "%1"=="" goto askq
if "%1"=="/?" goto help
if /i "%1"=="/h" goto help
if %1 GTR 0 if %1 LEQ 9999 if /i "%2"=="/q" set ans1=%1& goto quiet
if %1 GTR 0 if %1 LEQ 9999 set ans1=%1& goto breakout
if %1 LEQ 0 echo %1 is not a valid number & goto help
if not "%1"=="" echo.&echo "%1" is a bad parameter & goto help
goto end

:help
echo SLEEP runs interactively (by itself) or with parameters (sleep # /q )

echo.
goto end

:askq
set /p ans1=How many seconds to sleep? ^<1-9999^> 
echo.
if "%ans1%"=="" goto askq
if %ans1% GTR 0 if %ans1% LEQ 9999 goto breakout
goto askq

:quiet
choice /n /t %ans1% /d n > nul
if errorlevel 1 ping 1.1.1.1 -n 1 -w %ans1%000 > nul
goto end

:breakout
choice /n /t %ans1% /d n > nul
if errorlevel 1 ping 1.1.1.1 -n 1 -w %ans1%000 > nul
echo Slept %ans1% second^(s^)
echo.

:end

只需将其命名为sleep.cmd或sleep.bat并运行它

SLEEP 5包含在一些Windows资源工具包中。

TIMEOUT 5包含在一些Windows资源工具包中，但现在是Windows 7和8中的标准命令（不确定Vista）。

PING 1.1.1.1-n 1-w 5000>NUL对于任何带有TCP/IP客户端的MS-DOS或Windows版本，PING可用于延迟执行数秒。

NETSH badcommand（仅限Windows XP/Server 2003）或CHOICE

您可以使用VBScript，例如文件myscript.vbs：

set wsobject = wscript.createobject("wscript.shell")

do while 1=1
    wsobject.run "SnippingTool.exe",0,TRUE
    wscript.sleep 3000
loop

批处理文件：

cscript myscript.vbs %1

尝试Choice命令。自MSDOS 6.0以来，它就已经存在了，应该可以做到这一点。

使用/T参数指定超时（以秒为单位），使用/D参数指定默认选择并忽略所选选项。

如果用户在超时时间过去之前键入其中一个选择字符，可能会出现问题。部分解决方法是混淆情况——使用/N参数隐藏有效选项列表，并且在选项集中只有1个字符，这样用户在超时到期之前键入有效选项的可能性就更小了。

以下是Windows Vista上的帮助文本。我认为这在XP上是一样的，但看看XP计算机上的帮助文本来验证。

C:\>CHOICE /?

CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]

Description:
    This tool allows users to select one item from a list
    of choices and returns the index of the selected choice.

Parameter List:
   /C    choices       Specifies the list of choices to be created.
                       Default list is "YN".

   /N                  Hides the list of choices in the prompt.
                       The message before the prompt is displayed
                       and the choices are still enabled.

   /CS                 Enables case-sensitive choices to be selected.
                       By default, the utility is case-insensitive.

   /T    timeout       The number of seconds to pause before a default
                       choice is made. Acceptable values are from 0 to
                       9999. If 0 is specified, there will be no pause
                       and the default choice is selected.

   /D    choice        Specifies the default choice after nnnn seconds.
                       Character must be in the set of choices specified
                       by /C option and must also specify nnnn with /T.

   /M    text          Specifies the message to be displayed before
                       the prompt. If not specified, the utility
                       displays only a prompt.

   /?                  Displays this help message.

   NOTE:
   The ERRORLEVEL environment variable is set to the index of the
   key that was selected from the set of choices. The first choice
   listed returns a value of 1, the second a value of 2, and so on.
   If the user presses a key that is not a valid choice, the tool
   sounds a warning beep. If tool detects an error condition,
   it returns an ERRORLEVEL value of 255. If the user presses
   CTRL+BREAK or CTRL+C, the tool returns an ERRORLEVEL value
   of 0. When you use ERRORLEVEL parameters in a batch program, list
   them in decreasing order.

Examples:
   CHOICE /?
   CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."
   CHOICE /T 10 /C ync /CS /D y
   CHOICE /C ab /M "Select a for option 1 and b for option 2."
   CHOICE /C ab /N /M "Select a for option 1 and b for option 2."

我们不能等一下t/t 180吗？

waitfor/T 180暂停将导致“错误：等待‘暂停’超时”

waitfor/T 180暂停>nul将清除地毯下的“错误”

在Win95之后，等待命令应该在Windows操作系统中

在过去，我下载了一个名为sleep的可执行文件，在您将其放入路径后，它将在命令行上运行。

例如：sleep shutdown-r-f/m\\yourmachine尽管shutdown现在内置了-t选项
