忍不住用powershell了；囧

powershell "'共计时间:{0}' -f (([System.DateTime]'0:0:0') + (([System.DateTime]'%tt2%')-([System.DateTime]'%tt1%'))).GetDateTimeFormats('T')[0]"
复制代码

:: 计算时间,精确到秒
@echo off
color 1f
set tt1=%time:~0,-3%
calc.exe
set tt2=%time:~0,-3%
echo.
echo 开始时间: %tt1%
echo 结束时间: %tt2%
powershell "'共计时间:{0}' -f (([System.DateTime]'0:0:0') + (([System.DateTime]'%tt2%')-([System.DateTime]'%tt1%'))).GetDateTimeFormats('T')[0]"
echo.
