A date and time library based on the C++11/14/17 <chrono> header

Arduino library to facilitate time zone conversions and automatic daylight saving (summer) time adjustments.

NTP library for Arduino framework

Library for NTPClient to connect to an NTP time-server. Get time from a NTP time-server and keep it in sync. For ESP8266/ESP32, nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, etc. besides AVR, using ESP WiFi, WiFiNINA, Ethernet W5x00, ENC28J60, LAN8742A, ESP8266/ESP32 AT-command WiFi.

NTP Client library for ESP8266 with full timezone support

Rcpp interface to CCTZ library

Library to facilitate time zone conversions and automatic daylight saving (summer) time adjustments. For ESP8266, ESP32, WT32-ETH01 (ESP32 + LAN8720), SAMD21, SAMD51, nRF52, STM32F/L/H/G/WB/MP1, Teensy, SAM DUE, RTL8720DN, RP2040-based (Nano_RP2040_Connect, RASPBERRY_PI_PICO), Portenta_H7 (Ethernet or WiFi) boards, etc. using W5x00/ENC28J60/LAN8…

A NTP/Timezone extension to @tzapu's WiFiManager

Small Arduino Timezone library that supports POSIX TZ strings

Manages local time and DST settings for Particle IOT devices. Sets timezone based on the device's return IP address, by GPS coordinates, or by timezone ID. Data is obtained from public web-sites.

Class for working with date and time according to the Internet standard

WiFI Clock, synchronized with NTP, WiFi and timezone settings via web interface. Auto access point mode. Arduino-OTA updateable.

Print date and time information on the Windows command line

Uses Google maps API and NTP to determine time, timezone, daylight saving, latitude/longitude, physical address (still work in progress, code not beautiful but works)

This is an adaption of Arduino Timezone Library
