Different mechanisms are used for time management in the RevPi. They serve different purposes and complement each other.

RTC, NTP, and PTP refer to the time management of the RevPi base module. Expansion modules do not have their own time management.

Function Description

RTC (Real-Time Clock)

Stores date and time hardware-based and provides the time at system start.

NTP (Network Time Protocol)

Synchronizes the system time over the network with a time server.

PTP (Precision Time Protocol)

Synchronizes devices in the network with high accuracy in microsecond range.
Supported on RevPi Connect 4 and RevPi Connect 5.
