Clock Skew
The difference between local clocks on different machines in a distributed system, typically caused by hardware oscillator drift, NTP synchronization delays, or virtual machine scheduling jitter. It can lead to data consistency issues in time-sensitive judgments such as TTL.

Clock skew refers to differences between the local clocks of different machines in a distributed system, usually caused by hardware crystal oscillator drift, NTP synchronization delay or VM scheduling jitter; even with NTP enabled on all nodes, deviations of seconds or even hundreds of milliseconds remain common.
