Why does setTime add an hour?

Question

This code results in an output of 1. Why is this when the argument to setTime is the number of milliseconds added to midnight Jan 1 1970? Surely it should be 0?

var d = new Date();

d.setTime(0);

console.log(d.getHours());

Answer 1

you can do this

    var d = new Date();
    
    d.setTime(0);
    
    console.log(d.getUTCHours());

thing is getHours give time at your timezone(local timezone), to get the UTC time just change it to getUTCHours
