ezTime — pronounced "Easy Time" — is a very easy to use Arduino time and date library that provides NTP network time lookups, extensive timezone support, formatted time and date strings, user events, millisecond precision and more.
I have the following function to calculate the civil dawn time:
#include <ezTime.h>
#include <ESP8266WiFi.h>
#include <SolarCalculator.h>
calculate dawn(t){
Serial.println("calculating dawn");
Serial.println("time passed to calculate dawn: " + dateTime(t));
double tr, dawn, dusk;
calcCivilDawnDusk(t, latitude, longitude, tr, dawn, dusk);
Serial.println("t after calculation: " + dateTime(t));
dawn += 1.0;//needs to be offset
Serial.print("day t: ");
Serial.println(day(t));//this prints the wrong value, 21(today) instead of 22 on my test run
....
}
I got some suspicious result, that's why i inserted the print statements and i got the following:
calculating dawn
time passed to calculate dawn: Tuesday, 22-Nov-2022 00:00:01 CET
t after calculation: Tuesday, 22-Nov-2022 00:00:01 CET
day t: 21
It seems that day(t) ignores the t parameter and uses the current time.
If this is my error that i missed somewhere i apologize and I'll be grateful if you point it out to me
