Hi Team,
Does it have some functions to calculate the working time from the starting point on nrf52850 chips?

From your other tickets it seems that you are using the nRF5 SDK, in which case you can see a demonstration of the RTC peripheral usage in the RTC peripheral example, or you could read about the app_timer library here - the app_timer library is also extensively used in the BLE peripheral examples in the SDK, if you want to see its usage demonstrated.
Best regards,
Karl
