Measure execution time for a command, like `time` on Linux.

timecmd.bat

@echo off
setlocal

for /f "tokens=1-4 delims=:.," %%a in ("%time%") do (
    set /a "start=((((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100)"
)

cmd /c %*

for /f "tokens=1-4 delims=:.," %%a in ("%time%") do (
    set /a "end=((((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100)"
)

set /a duration=%end%-%start%
set /a seconds=%duration% / 100
set /a centi=%duration% %% 100
if %centi% lss 10 set centi=0%centi%

echo =================================
echo Execution Time: %seconds%.%centi% seconds
