ESP32Time

An Arduino library for setting and retrieving internal RTC time on ESP32 boards

Functions

ESP32Time rtc(offset); // create an instance with a specifed offset in seconds
rtc.offset;	// get or modify the current offset
setTime(30, 24, 15, 17, 1, 2021);  // 17th Jan 2021 15:24:30
setTime(1609459200);  // 1st Jan 2021 00:00:00
setTimeStruct(time);	// set with time struct

getTime()          //  (String) 15:24:38
getDate()          //  (String) Sun, Jan 17 2021
getDate(true)      //  (String) Sunday, January 17 2021
