Timestamps play an important role in digital investigations, since they are necessary for the correlation of evidence from different sources. Use of timestamps as evidence can be questionable due to the reference to a clock with unknown adjustment. This work addresses this problem by taking a hypothesis based approach to timestamp investigation. Historical clock settings can be formulated as a ...

We examined influence of a clock ticking on task performance using a laboratory experiment. We determined performance at various clock speeds using a trick clock that allowed us to control the speed of the ticking. We found that which the clock ticked, and people performed more slowly with a slow clock. We demonstrated that common environmental stimuli we encounter in life, such as the ticking ...
