Esp-idf: system_get_rtc_time()

[ESP32DE]

hi guys
happy new year!

test the system_get_rtc_time(void)
in time.c ( newlib )
https://github.com/espressif/esp-idf/blob/master/components/newlib/time.c#L203
uint64_t system_get_rtc_time(void)

in kolban's esp32 book i read the function
with inlcude esp_system.h

system_get_rtc_time
Get the real time clock cycles.
uint32_t system_get_rtc_time()
Page 372

---

Page 373
Retrieve the number of real-time clock cycles. For example, if the value returned by
system_rtc_clock_cali_proc() is 5.75µS then if the system_get_rtc_time() returns
100, then 575µS of wall clock time has passed since the clock was started.
Includes:
• esp_system.h

uint32_t system_get_rtc_time(void)

but there is no function in the system
https://github.com/espressif/esp-idf/blob/master/components/esp32/include/esp_system.h

same, there is no declare in the newlib/include/time.h
https://github.com/espressif/esp-idf/blob/master/components/newlib/include/time.h

do we miss / do we wrong here a part?

txs

best wishes

the esp_system api was removed:

This function was intentionally removed,
as the functionality is now provided by POSIX gettimeofday function.

The book of notes on the ESP32 has been amended to remove the system_get_rtc_time() function reference.

Thanks @nkolban !

how can I access the rtc timer of ULP in deep sleep mode?
