How to switch to system timestamps, instead of RTOS timestamps, in logging?

[cyberman54]

Is there a way to have timestamps, based on system (not RTOS) time in logs?

I found logging in ESP32-IDF is controlled by defines in SDKonfig, while arduino-esp32 framework is using RTOS timestamp logging.

Im am using ESP_IDF logging style (USE_ESP_IDF_LOG set).

Is there a way to override the arduino-esp32 setting and switching to system time logging?

Short answer: No.
CONFIG_LOG_TIMESTAMP_SOURCE_RTOS is used in esp_log.h. That is at the IDF level. Modifications to sdkconfig.h only apply if you recompile the base IDF binaries. For that level of control it's better to code with IDF and possibly "Arduino as IDF component".
