Built-in Examples. Learn how to get time, date, day of week, month, year in Arduino using Real-Time Clock DS3231 module, how to program Arduino step by step. Sadly, the documentation provides NO help. The tm input is a TimeElements variable which breakTime fills The millisDelay library is part of the SafeString library V3+. The code is derived from the Playground DateTime library but is updated to provide an API that is more flexible and easier to use.
