Hello ! First of all, thank you for this librairy ! In the documentation, it is said that the RTC memorize power outage time/ date and when the power comes back on, how do we obtain these times/dates ?

Hello sounox,

The functions [getPowerDown()](https://github.com/SV-Zanshin/MCP7940/wiki/getPowerDown()) and [getPowerUp()](https://github.com/SV-Zanshin/MCP7940/wiki/getPowerUp()) will return those date/time values to you.
