The Raspberry Pi is not included.

Technical Details
Instruction
As we know, the Raspberry Pi itself does not have the timing circuit. After rebooting the Raspberry Pi, its time will go back 1970 or won't run at all. However, with this DS3231 Real Time Clock Module installed, it can still be punctual timing without network timing service, which solves the problem of timing.

Instructions are a little lacking, but easy to work through. I didn't need to remove anything from the Blacklist as the instructions indicated. The rest of the instructions worked though. At first, the time was not current, but running a "sudo hwclock --s
Product works great.

1. Ensure you already installed the RTC module. If you haven't, turn OFF the Pi first, then install the module. Best explanation here is to just look at the photo to see how the module is oriented. 2. Raspian Wheezy and Jessie support a realtime clock. T
Worked just fine for the Pi 3. I needed the real-time clock due to a project I'm working on. Didn't even realize the Pi 3 doesn't come with a hardware clock. Last time I dealt with that was in the early 90s... but anyway, this isn't plug and play, you do need to manually do some configuration editing to make the hardware clock active. You can google around and get the same info to install but I'm posting here mostly for myself so I can easily reference this in the future. Beware that a lot of what you find online are obsolete for the Pi 3! So be careful. This was taken off the thewaylabs courtesy of Dr. Marcus Durham and slightly adapted by me. Where it has a >> means you enter those commands into the shell verbatim.

At first, the time was not current, but running a "sudo hwclock --systohc" fixes that. To make this work on boot, you have to edit the "/etc/rc.local" file manually, instructions didn't work here. Add the following before the "exit 0" lines: echo ds1307 0
