For example, your laptop and computer have a little coin-battery-powered 'Real Time Clock' (RTC) module, which keeps time even when the power is off, or the battery removed. To keep costs low and the size small, an RTC is not included with the Raspberry Pi. Instead, the Pi is intended to be connected to the Internet via Ethernet or WiFi, updating the time automatically from the global ntp. DS1307RTC works with the DS1307, DS1337 and DS3231 real time clock chips. The DS1307 chip only works with 5 volt power. The DS1337 and DS3231 can use 3.3 or 5 volts. Teensy 3.0 has a built-in RTC, so the DS1337 offers little benefit. However, the DS3231 includes a temperature compensated crystal, so it is recommended for applications requiring high accuracy.
