## 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

getDateTime()      //  (String) Sun, Jan 17 2021 15:24:38

getDateTime(true)  //  (String) Sunday, January 17 2021 15:24:38

getTimeDate()      //  (String) 15:24:38 Sun, Jan 17 2021

getTimeDate(true)  //  (String) 15:24:38 Sunday, January 17 2021

getMicros()        //  (unsigned long)    723546

getMillis()        //  (unsigned long)    723

getEpoch()         //  (unsigned long)    1609459200

getLocalEpoch()    //  (unsigned long)    1609459200 // local epoch without offset

getSecond()        //  (int)     38    (0-59)

getMinute()        //  (int)     24    (0-59)

getHour()          //  (int)     3     (1-12)

getHour(true)      //  (int)     15    (0-23)

getAmPm()          //  (String)  PM

getAmPm(true)     //  (String)  pm

getDay()           //  (int)     17    (1-31)

getDayofWeek()     //  (int)     0     (0-6)

getDayofYear()     //  (int)     16    (0-365)

getMonth()         //  (int)     0     (0-11)

getYear()          //  (int)     2021

getTime("%A, %B %d %Y %H:%M:%S")   // (String) returns time with specified format
