Answer 1

loadCSV(`counters_test_directory_${TimeNow}.log`);

var prex = document.querySelector('pre');

var DateNow = new Date();
DateNow.setHours(DateNow.getHours()-1);

var TimeNow=DateNow.getFullYear() + "" + (DateNow.getMonth()+1) + "" + DateNow.getDate();
alert(`counters_test_directory_${TimeNow}.log`);
// The source of this function is NOT given.
//loadCSV(`counters_test_directory_${TimeNow}.log`);

prex.innerHTML += '\n\n';
prex.innerHTML += TimeNow;

<pre>
</pre>
