REM date /t returns Day_of_Week, Month, Day and year in our
REM Win2000 installation.
REM This depend on a date format and we need a small trick
REM to extract the format from "date" command.

for /f "tokens=1,2,3,4* delims=.:/- " %%i in ('date /t') do (
for /f "skip=1 tokens=2-4 delims=/-,()." %%x in ('echo.^|date') do (
set day=%%i&set %%x=%%j&set %%y=%%k&set yyyy=%%l))


for /f "tokens=1,2* delims=: " %%i in ('time /t') do (
set hh=%%i&set min=%%j )

REM After this mess, we have min,hh,day,dd,mm and yyyy envariables.

echo Danes je petek, izvaja se varnostno kopiranje
