Feature Request, Make Boot Button Publish Several Kinds Of Messages

[ForrestErickson]

Summary, Press Button To Send Messages

This set of MQTT messages form an announcement for attendance in Discord

Details

Single press sends message, "a2Yehya is in Discord now" and with the date and time. This is an "problem" level message
Double press sends message, "a1Yehya has left Discord at" and with the date and time. This is an "Information" level message
Long press sends message "a5Yehya wants to meet in Discord as of " and the date and time.

Network time might be found by these methods suggested by and AI

Several libraries are available to synchronize your Arduino board with Network Time Protocol (NTP) servers. The best choice depends on your specific hardware (e.g., ESP32, ESP8266, or standard Arduino with an Ethernet shield). [1, 2, 3, 4]

Popular NTP Libraries

• NTPClient (by Fabrice Weinberg): The most common choice for general-purpose NTP synchronization. It is compatible with all architectures and allows you to fetch Unix epoch time and keep it in sync at custom intervals.
• ezTime: An all-in-one library that simplifies NTP lookups, timezone support, and Daylight Saving Time (DST) adjustments. It is highly recommended for projects that need formatted date strings without complex manual calculations.
• NTPClient_Generic: A modified version of the original NTPClient designed to work with a wider range of hardware, including SAMD21/SAMD51, STM32, Teensy, and various Ethernet shields.
• NTP by sstaub: This library supports built-in ESP32/ESP8266 RTC synchronization, making standard C time functions (like ) work automatically. [5, 6, 7, 8, 9]

Built-in Options (No Library Required) [10]

If you are using ESP32 or ESP8266 boards, you do not necessarily need a third-party library. The official board packages include native support for NTP:

• configTime(): This built-in function allows you to sync the system time directly with an NTP server by specifying the timezone offset and DST rules in your function.
• UNO R4 Minima RTC: Newer boards like the UNO R4 have a built-in Real-Time Clock that can be used alongside network-provided time. [12, 13, 14, 15, 16]

Comparison Table

Library [5, 6, 9, 11, 13] | Best For | Key Features -- | -- | -- NTPClient | Universal Use | Simple, widely documented, works on all boards. ezTime | Complex Time | Automated DST, timezone support, and easy formatting. NTP (sstaub) | ESP32/ESP8266 | Syncs with internal RTC; uses standard C time functions. Native configTime | ESP32/ESP8266 | No extra library footprint; handled by the ESP core.

Installation

To install any of these, open the Arduino IDE, go to Sketch > Include Library > Manage Libraries..., and search for the library name. [17, 18]
