Problem Description

Any Ticker tasks fire OK if time is short (tested up to 60 seconds (60 000ms)). However, when I try to control the brightness after sunset, the time gets big (for example 44944 sec (44 944 000ms)) & the same task no longer start. The code below is not exactly what I have in my project, but close.

MCVE Sketch

#include<Arduino.h>#include<Ticker.h>Ticker ticker_autoBrightness;uint32_t timeSec =44079;//12h:14m:39svoidsetup() {pinMode(2, OUTPUT);task_clockDayBrightness();}voidloop() {//empty}voidtask_clockDayBrightness(){digitalWrite(2, LOW);//turn LED on  ticker_autoBrightness.once_scheduled(timeSec, task_clockNightBrightness);}voidtask_clockNightBrightness(){digitalWrite(2, HIGH);//turn LED off  ticker_autoBrightness.once_scheduled(timeSec, task_clockDayBrightness);}
