AC Dimmer time control

This works.
I delete one of the dimmers in the sketch.
I changed the values for the dimmer output to test if the time is working oke.

#include <TimeLib.h>
#include <TimeAlarms.h>

//AlarmId id;

int AC_LOAD1 = 10; // Output to Opto Triac pin
volatile int dimming1 = 128; // Dimming level (0-128) 0 = ON, 128 = OFF


void setup() {

  // Initialize Serial and wait for port to open:
  // Bridge.begin();
  Serial.begin(115200);

  setTime(8, 29, 45, 1, 1, 11); // set time to Saturday 8:29:30am Jan 1 2011

  // create the alarms, to trigger at specific times
  Alarm.alarmRepeat(8, 30, 0, LightOn); // 8:30am every day
  Alarm.alarmRepeat(8, 30, 15, LightOff); // 8:30;30am every day
  Alarm.alarmRepeat(8, 30, 30, LightOn1); // 8:30am every day
  Alarm.alarmRepeat(8, 30, 45, LightOff1); // 8:30;30am every day

  pinMode(AC_LOAD1, OUTPUT); // Set the AC Load as output


  attachInterrupt(0, zero_crosss_int, RISING); // Choose the zero cross interrupt # from the table above
}

void loop() {
  Serial.print("min/sec ");
  digitalClockDisplay();
  Serial.println("dimming values");
  Serial.print(dimming1);
  //Serial.print(":");
  //Serial.println(dimming2);
  Alarm.delay(1000); // wait one second between clock display
}

// functions to be called when an alarm triggers:
void LightOn() {
  dimming1 = 0; //Full = 0  
}

void LightOff() {
  dimming1 = 50; //Off = 128 
}
void LightOn1() {
  dimming1 = 100; //Full = 0  
}

void LightOff1() {
  dimming1 = 128; //Off = 128 
}

void digitalClockDisplay() {
  // digital clock display of the time
  //Serial.print(hour());
  printDigits(minute());
  Serial.print(":");
  printDigits(second());
  Serial.println();
}

void printDigits(int digits) {
  //Serial.print(":");
  if (digits < 10)
    Serial.print('0');
  Serial.print(digits);
}

void zero_crosss_int() // function to be fired at the zero crossing to dim the light
{
  sei(); //re-enable interrupts

  // Firing angle calculation :: 50Hz-> 10ms (1/2 Cycle)
  // (10000us - 10us) / 128 = 75 (Approx)
  int dimtime1 = (75 * dimming1);
  

    delayMicroseconds(dimtime1);
    digitalWrite(AC_LOAD1, HIGH);
    delayMicroseconds(10);
    digitalWrite(AC_LOAD1, LOW);
    
  
}
