invalid use of member (did you forget the '&'?)

Projects Programming
1

For the life of me I can't figure out why this sketch will not compile.
I'm sure the problem is in these lines.

int time();

or

time = ((now.hour * 60) + now.second);

When verifying sketch I get the error, "invalid use of member (did youforget the '&'?)

Any help would be great. Thanks!

// Date and time functions using a DS1307 RTC connected via I2C and Wire lib

#include <Wire.h>
#include "RTClib.h"

RTC_DS1307 RTC;

int time();

void setup () {
    Serial.begin(9600);
    Wire.begin();
    RTC.begin();
    


  //if (! RTC.isrunning()) 
  {
    Serial.println("RTC is NOT running!");
    // following line sets the RTC to the date & time this sketch was compiled
    RTC.adjust(DateTime(__DATE__, __TIME__));
  }
}

void loop () {
    DateTime now = RTC.now();
   
    time = ((now.hour * 60) + now.second);
    
    
    if(now.hour = 0){                              //0th hour
      if((3450 <= time < 3549)||(0 <= time < 150)){
        Serial.println("TWELVE O'CLOCK");

Is time supposed to be a number? If so, lose the parentheses in the

int time();

line

The parentheses mean that time is a function, which I don't think you want.

EDIT:
also, this line (and similar) won't do what you want

 if(150 <= time < 450){

You need to be explicit and say

if (150 <= time && time < 450) {

You're right.
time is supposed to be a number. I made the changes you suggested, however, I am still getting the same error on the line

time = ((now.hour * 60) + now.second);

invalid use of member (did you forget the '&'?)

Thanks again.

the hour and second method of DateTime are functions, so you need parentheses there.

time = ((now.hour() * 60) + now.second());

The primary syntactical difference between a function and a variable is the argument list (which is empty here)
