Puck.js PowerMeter to HomeAssistant

Hello
Here is my project. Not sure if I should be posting a code here or in pastebin. Let me know so that I will do it next time =)
Anyway. I have this working by using Puck.js that counts pulses on my smart power meter and transmits them for ESPHome running ESP32 board to pickup and process into HomeAssistant.
At the moment have an issue with with the code (which is reused example code plus few extras) - it is set to keep track of pulses (hourly, daily etc), but it does not reset when the hour is changed over. Which causes incorrect values - it increments what was already there from the previous day =(
Can someone skim through the code and suggest any optimizations and help me with counter resets for daily pulses?

function Counter() {
  this.clear();
}
/// Clear the counters back to zero
Counter.prototype.clear = function() {
  this.totals = {
    count : 0,                // Overall count
    year : new Uint32Array(12), // each month of the year (0..11)
    week : new Uint32Array(7), // each day of the week (0..6)
    month : new Uint32Array(31), // each day of the month (0..31)
    day : new Uint32Array(24), // each hour (0..23)
  };
  this.historyPeriod = 60*60*1000; // 1 hour in milliseconds
  this.history = new Uint32Array(96); // last 96 hours
  this.historyTime = 0;
  this.lastUpdate = new Date.now();
};

Counter.prototype.inc = function(n) {
  if (n===undefined) n=1;
  
  var t = this.totals;
  var d = new Date();
  // Totals by time period
  t.count+=n;  
  t.year[d.getMonth()]+=n;
  t.week[d.getDay()]+=n;
  t.month[d.getDate()-1]+=n;
  t.day[d.getHours()]+=n;
  print("Day:"+t.day);
  print("Month:"+t.month);

  pulseHour=t.day[d.getHours()];
  pulseDay=t.month[d.getDate()-1];
  
  // Rolling history
  this.historyTime += d.getTime()-this.lastUpdate;
  this.lastUpdate = d.getTime();
 
  var steps = Math.floor(this.historyTime / this.historyPeriod);
  
  if (steps>=0) {
    this.historyTime -= steps*this.historyPeriod;
    var h = this.history;

    h.set(new Uint32Array(h.buffer, 4*steps), 0);
    h.fill(0, h.length-steps);
    h[h.length-1]+=n;
  }
};
