I work with Raspberry Pi 2 model B v1.1 and I searched about a RTC to keep time even in the case of a power outage or a loss of internet connection. I found that I must buy a RTC chip with a battery. But recently I heard that my Raspberry Pi already contains a RTC. But is it right? If so, where is its location? I don't see anything called RTC on my chip.
None of the Raspberry Pi models have a built-in real time clock.
Does the Raspberry Pi 2 model B v1.1 have an internal RTC?
