RTC Library for a Pro Mini Available?

Is there a RTC Library for a Pro Mini? I can't seem to find any reference to it so I assume there isn't but wanted to check.

Other wise I'll use a RTC Module.

Thanks

Arduinos do not have a built in RTC so why would there be a library unless you are using an RTC ? There is a time library that provides some time based functions but Arduinos are not good at keeping time without an RTC or other means to obtain the time from an accurate source.

Well that's not actually true. If you go to the RTC Library reference it states that certain boards, Zero, MKRZero & MRK100, do have an internal RTC. Maybe I misunderstood that.

I also looked at the RTC libraries available through the Arduino site and there are several but again they seem to be only for certain boards.

As I stated in my original post I assume there isn't but I have found that people with more knowledge with the product than I, know that you can do certain things not referenced. That's why I asked.

There are two Pro Minis out there: the Nano and the Mega. I think almost any RTC module would work with the RTC library for either board.

That makes absolutely no sense at all. The Nano, Pro Mini and Mega are all completely different boards, with completely different form factors....

What I was saying was there is a Nano Pro Mini and a Mega2560 Pro Mini and if you buy an RTC module there are libraries for both boards that will likely work. Makes perfect sense to me.

There is a Nano. There is a ProMini. There is a Mega2560. Three different boards, three different form factors, three completely different pinouts, three different specs, even different processors. There is no such thing as a "Nano Pro Mini", nor is there a "Mega2560 Pro Mini". Where are you getting that from?
