time fault

time fault (plural time faults)

1. (equestrianism) A penalty given in which a rider does not complete the course in the time allowed that is set by the course designer.
   • 2001, Laura Moore, Ride a Dark Horse, page 286:

     For instance, a refusal was three points, but as it generally took the rider precious seconds to get his horse over the refused fence, a time fault of four points could be expected.

   • 2010, Bradley Berner, Blood on the Irons:

     If the rider is over the time allowed he or she is penalized 1⁄4 time fault for every second over the limit.

   • 2021, James Patterson, The Horsewoman:

     If I went over by a tenth of a second, I got a time fault and some other horse would be the last qualifier for the Grand Prix.

2. (sciences, engineering) A fault in the timing of an automated system.
   • 2007, Hong-Yue Zhang, Fault Detection, Supervision and Safety of Technical Processes, page 628:

     Finally, the bottom window of the figure displays the time fault estimation results.

   • 2013, Magdi S. Mahmoud, ‎Yuanqing Xia, Analysis and Synthesis of Fault-Tolerant Control Systems, page ix:

     There are significant numbers of works addressing discrete time fault detection problems using Kalman filter techniques [40, 41, 42]. Similar to the multi-objective design problem of continuous time fault detection, robustness in discrete time fault detection is also a very important issue but difficult to handle.

   • 2015, Stefan Schneider, Automatic Modeling and Fault Diagnosis of Timed Concurrent Discrete Event Systems:

     In closed-loop DES, timed fault isolation is the determination of time fault symptoms based on observed and modeled timed system outputs. The time fault symptoms refer to time behavior of I/Os that is inconsistent with the modeled one.

3. (science fiction) An anti-gravity singularity deep beneath an undisclosed place on Earth, described as the darkness behind the resurrection of Earth.
