Timestamp service for ESP32 that works without a dedicated RTC module. Starts from build time on every boot, then corrects via SNTP sync or manual set — whichever suits the application. All corrections are explicit and observable via jump callbacks, safe for logging systems.
Standalone ESP-IDF captive portal component. Registers all standard OS captive-portal detection endpoints on an esp_http_server instance and redirects clients to the device's built-in web interface with a single function call. Supports iOS, macOS, Android, Windows, Firefox, and Chrome.
