latency

n
1: (computer science) the time it takes for a specific block of data on
a data track to rotate around to the read/write head [syn: rotational
latency]
2: the time that elapses between a stimulus and the response to it [syn:
reaction time, response time, latent period]
3: the state of being not yet evident or active

No apparent references to "unexplained" in association with the word
latency.
