Time commands and its relation with timers in the ESP32 Board (Arduino IDE)

Hi.

The arduino board uses the millis () function, using Timer 0.The ESP32 board has two timer group, each one with 2 timers (Timer Group 1: TIMER 0 - TIMER 1, Timer Group 2: TIMER 2- TIMER 3). The question is what timers are used when using the following commands (ARDUINO IDE) ?

a) esp_timer_get_time();
b) xTaskGetTickCount();
c) millis();
d) micros();
e) esp_log_timestamp();

You have the source code on your PC. You can look.
