I used the "set time" example to test my RTC but on every other read the date is garbage. Here's the output of the program:

(unknown day) 2011-84-11 11:100:19
Thursday 2017-08-17 17:41:33
(unknown day) 2011-84-11 11:100:20
Thursday 2017-08-17 17:41:35
(unknown day) 2011-84-11 11:100:21
Thursday 2017-08-17 17:41:37
(unknown day) 2011-84-11 11:100:22
Thursday 2017-08-17 17:41:39
(unknown day) 2011-84-11 11:100:20
Thursday 2017-08-17 17:41:41
(unknown day) 2005-42-05 05:130:50

I've not modified the code or the example. I changed the battery that came with the unit but that has not solved it.

First of all thanks for spending the time to create this library and donating it to the world. It helped me get up and running very rapidly with this cheap RTC board.
Just a minor amendment, I believe there is an error with the switch case, which defines the name of the day of the week, starting on line 33 of "set_clock.pde".
I noticed the day of the week was displaying as Tuesday when it was actually Thursday.
I believe this is the correct order.
Monday = 0, Tuesday = 1, Wednesday = 2, Thursday = 3, Friday = 4, Saturday = 5, Sunday = 6.

This would be helpful and simplify one of the examples

Master does not work with my DS1302 9905A3 163AC. Shows strange date, random seconds. However, previous commit f4794ec works fine

Sorry, it was power issue

Compile files: 'const class String' has no member named 'c_str'

This is just an FYI, I don't need a fix. I just changed dayAsString to dayAsInt and moved on. I imagine the Arduino folks made a change to the String implementation. Thanks for providing this library!

When I try to compile the code I get an error message saying " expected identifier before 'void' " and it's pointing at

case Time::kSunday: return "Sunday";

Did I install this wrong or maybe missing any files?

I have been trying to set-up my DS1302 module this evening. I used the example set_clock.ino and connected the pins as shown in the diagram to the arduino. I also changed the date/time in the code on line 68 from: Time t(2013, 9, 22, 1, 38, 50, Time::kSunday); to Time t(2018, 11, 18, 17, 20, 00, Time::kSunday);

The serial monitor output just repeats: (unknown day) 2000-00-00 00:00:00. Am I missing something?

I modified the sample sketch to run every one sec. There's a bug where every other sec and every other minute is wrong. See attached image.
