Timing failure
Script error: No such module "Unsubst". Timing failure is a failure in a time related process in machinery or computing. This can be where timing failures refer to "a situation where the environment in which a system operates does not behave as expected regarding the timing assumptions, that is, the timing constraints are not met."[1]
Computing
In computing, it refers to a timing failure or error in process, or part of a process, in a synchronous distributed system or real-time system to meet limits set on execution time, message delivery, clock drift rate, or clock skew.[2][3][4] Asynchronous distributed systems cannot be said to have timing failures as guarantees are not provided for response times.
Machinery
In engineering and mechanics a timing failure typically refers to an issue with the timing belt of an engine.[5][6]
