Hey guys,
- I need to record many time interval ?, can i generate system time and use it to record all of my time intervals?
- If I want to send all of the time intervals to App via BLE, how could I do ?

Hey guys,

You can implement your own system time by starting TIMER1/TIMER2 or RTC1 when the system starts. Using RTC1 might be good selection but it will have a overflow every 582 hours if you use the prescaler of (2^12 -1).
If you use TIMER1 or TIMER2 then those will keep HFCLK enabled in sleep modes making your power go up.
there is no system time function in SDK or C library that uses nrf clocks. You have to implement your own
use one of examples like ble_app_hrs and use that service to send your tailored data to APP. There are many tutorials/blogs and documentation in devzone to give you a kickstart.
Thanks Aryan. If I want to to use timer to timing when the softdevice is enable, is it different from when the software is disable? How could i do?
