alarmd is not an option - the trigger for this script is dbus event - i do not want it to run in certain hour (if i did - i would know what time it is running).

I will definitely need help in making such a command in shell script (format the strings of course) since i am very weak at this:
the .sh script will be something like this is pseudo code:

if [ time is between 16:00 to 18:00 ]; then
[run the command]
fi

Thanks!
