RTCs often provide alarms and other interrupts. One of these usually has battery backup power so that it tracks the time even while the computer is turned off. These are called 'Real Time Clocks' (RTCs). No need to pay the inflated price of the chronodot though. Most computers have one or more hardware clocks which record the current 'wall clock' time. The DS3231 is accurate to 2ppm at 0-40 ☌ range. This is the battery-backed clock that keeps time even when the.

DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. Two clocks are important in Linux: a hardware clock, also known as RTC, CMOS or BIOS clock. When setting the alarm, you can click the 'Test' button to preview the alert and check the sound volume. The alarm message will appear, and the preselected sound will be played at the set time.
