Does Raspberry Pi have real-time clock?
Time keeping
Because the Raspberry Pi is designed as an ultra-low cost computer, it lacks the little coin-battery-powered ‘Real Time Clock’ (RTC) module that sits in your laptop or desktop computer. Instead, the Raspberry Pi updates the time automatically from the global NTP (Network Time Protocol) servers.
How do I use my Raspberry Pi as an alarm clock?

Does Raspberry Pi keep time without internet?
Although the NTP service can keep the time accurate when the Raspberry Pi is connected to the network, it can’t do so when the device is offline. To keep the time accurate when the device is offline, you need to use a USB RTC Dongle battery-backed RTC module.
Can a Raspberry Pi work 24/7?
Re: Operating 24/7
Yes, it is completely normal to run a Pi 24/7. Even for years at a time. They use so little power that it’s not worth turning them off when not in use.
Can you use a Raspberry Pi as a security system?
In order to detect the temperature, humidity, and motion information of a house, we use PIR motion sensor and temperature and humidity sensor and connect them to the Raspberry Pi through GPIO. PIR sensors, often referred to as “Passive Infrared” sensors, enable you to sense motion.
How do I turn my Raspberry Pi into a GPS tracker?
