Ok.
I got it working!
Had to get the old time library (1.5.0), then it worked perfectly!
The latest time library does not work like that however.
How do I then use it in my code that displays the time?
It looks like it is not seeing the DS1302 library.
I'm guessing it's because you haven't created an object .
Here is a snippet showing how that's done from the example included with that library:
const int kCePin = 5; // Chip Enable
const int kIoPin = 6; // Input/Output
const int kSclkPin = 7; // Serial Clock
// Create a DS1302 object.
DS1302 rtc(kCePin, kIoPin, kSclkPin);
You will have to input the pins that you used.
Edit: didn't see that you replied
Show us your current code.
The reason I asked
is because up till now I've been using another RTC library in my weather station, but now that I've set the time from the compilier, my LCD does not display the correct time (ie. the date is 45/17/2077)

That's the code for the other library. Show us your attempt at the code using the library you want to use.
@Hutkikz
I was hoping I could set it with one library, then read it with the other one.
Is that not going to work?
I don;t think so but you could try it 
This project has complete code to set the clock from operator input. The last step is synch that you can hit to a fraction of a second.
@Hutkikz
That's what I did, but it displays impossible dates, so I guess it won't work.
To begin with, I uploaded the DS1302 library Serial example, and it says that the time has not been set.
Serial monitor:
DS1302RTC Read Test
RTC module activated
The DS1302 is stopped. Please run the SetTime
example to initialize the time and begin running.The DS1302 is write protected. This normal.
I'm not sure why the first line is bold, sorry.
@madmark2150
That uses yet another library.
Is the Battery good? when it is set does it keep time after power to the arduino has been removed?
The setting code is independent of library. Lift the time set logic and just substitute the driver of your choice. The operation of them is the same at this level.
Hmmm, once set it should remain set unless it's battery is removed/dead.
Hmmm, once set it should remain set unless it's battery is removed/dead.
@Hutkikz
That's kinda what I thought.
@madmark2150
Your code displays too many errors, which I'm not repairing unless I have to.
@Hutkikz
It stays set with the library I originally used.
It compiles and runs flawlessly for me ...
Did you change it to my library (post #33)?
I have figured out how to get it within half a second of the real time. I tell the RTC a time two minutes ahead of time, then reset two seconds before my computer displays that exact time. It then displays within half a second of the real time.
(I also then comment out the line that sets the time so it doesn't reset every time the board does)
Thanks everyone for your help!!
