ezTime — pronounced "Easy Time" — is a very easy to use Arduino time and date library that provides NTP network time lookups, extensive timezone support, formatted time and date strings, user events, millisecond precision and more.

High precision and accuracy, open source, online, extensible and low cost homebrew automation on top of ESP8266 microchip.

ESP8266 based dot matrix clock with weather

Fully Asynchronous UDP Library for WT32_ETH01 (ESP32 + LAN8720). The library is easy to use and includes support for Unicast, Broadcast and Multicast environments.

This library enables you to use RTC from RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO. This RP2040-based RTC, using Interrupt, has no battery backup. Time will be lost when powered down. To need NTP-client to update RTC every start-up.
