Real Time Clock for Raspberry Pi
Since the Raspberry Pi is meant to be a low-cost system, many of the functionality that we are used to having on a machine have been omitted. A tiny coin-battery-powered (RTC) "Real Time Clock" module, for example, is built into your laptop and computer and keeps time even when the power is switched off or the battery is replaced. To keep costs down and the size minimal, the Raspberry Pi does not have an RTC. Instead, the Pi should be connected to the Internet via Ethernet or Wi-Fi, with the time being updated automatically from global ntp servers.
Important Update:
Competition for Young Makers in China and the United States in 2021
Without a network connection, you won't be able to keep the time for stand-alone activities if the power goes out. So, in this project, we'll show you how to use a low-cost battery-powered RTC to sync up on your Pi!

To keep costs down, the Raspberry Pi does not have a Real Time Clock module. Users would instead keep track of time by tracking the network when it is wired to Wi-Fi or Ethernet. We're going to use a third-party module.
We can advise SB Components' USB RTC for Raspberry Pi as the easiest, most precise, and fastest RTC device we've found!
This is a brilliant battery-powered real-time clock (RTC)that keeps time for your Raspberry Pi project even though the electricity goes out.
Data recording, clock building, time stamping, timers, and alarms are only a few of the applications. It works for any Raspberry Pi (or similar single-board computer)
