This RTC (Real Time Clock) module makes it very easy to keep track of time.

Note: As soon as the module is supplied with voltage, the chip activates and thus also the battery backup. From then on, the battery will last approximately one year (net, so with the module not being powered). If you do supply the module with power, the battery will of course last longer.
