System time

The system time can be updated, where applicable, by means:

• • I2C RTC

    • MCP794x (for example: http://bitwizard.nl/shop/I2C-RTC)

    • DS3231 (for example https://www.adafruit.com/product/3013)

  • NTP Client (see Network configuration)

  • Art-Net ArtTimeSync

  • UART GPS time

    • ATGM336H (or compatible)

    • ublox-NEO7

    • MTK3339 {for example: https://www.adafruit.com/product/746}

When there is none of the above, the system time is the uptime.
