make a counter / timestamp

[pca10056]

Hi
I'm brand new to use nrf52840, but hope there is one that can help i need a counter / timestamp. If it's a counter, it still has to count even if you do something else. To know when the last message from the server has been sent to see if it is still in the network
i am using bluetooth mesh.
Hope there is someone who can help
