RTC real-time clock

Question

I would like to ask you a question, that is, the RTC in the chip of 52832, in the case of non-power-off restart, is there any way to keep the RTC time and continue the timing?

Hi, 
 The RTC peripheral in the nRF52 series ICs are a low power timer (Real Time Counter), not a Real Time Clock. If the power is lost or the chip enters SYSTEM OFF sleep mode, all clock sources are shut down and the RTC will stop running. On a reset, all peripherals are reset. 
 Best regards, Jørgen
