How is ping actually measured?

So I have researched all I can find on ping and I cannot seem to find the level of detail I am looking for.

Basically I want to know if ping relies on NTP and system clocks on a network being in sync and just measures the difference in between time sent and recieved, or if there is a specific method to how the ICMP echo request and replies are measured so that a ping can be measured even if NTP is not working correctly and the times are not in sync?
