The thermal time hypothesis is a possible solution to the problem of time in classical and quantum theory as has been put forward by Carlo Rovelli and Alain Connes. Physical time flow is modeled as a fundamental property of the theory, a macroscopic feature of thermodynamical origin. [31] [32]
The year 2038 problem (also known as Y2038, [1] Y2K38, Y2K38 superbug, The Unix Y2K38 bug, [2] or the Epochalypse [2] [3] [4]) is a time computing problem that prevents some computer systems from representing times after 03:14:07 UTC on 19 January 2038.
The Network Time Protocol has an overflow issue related to the Year 2038 problem, which manifests itself at 06:28:16 UTC on 7 February 2036, rather than 2038. The 64-bit timestamps used by NTP consist of a 32-bit part for seconds and a 32-bit part for fractional second, giving NTP a time scale that rolls over every 2 32 seconds (136 years) and ...
Haldane's dilemma, also known as the waiting time problem, [1] is a limit on the speed of beneficial evolution, calculated by J. B. S. Haldane in 1957.
An epistemological problem with using causality as an arrow of time is that, as David Hume maintained, the causal relation per se cannot be perceived; one only perceives sequences of events. Furthermore, it is surprisingly difficult to provide a clear explanation of what the terms cause and effect really mean, or to define the events to which ...
There are some problems for which we know quasi-polynomial time algorithms, but no polynomial time algorithm is known. Such problems arise in approximation algorithms; a famous example is the directed Steiner tree problem, for which there is a quasi-polynomial time approximation algorithm achieving an approximation factor of () (n being the ...

Year 2038 problem: a time formatting bug in computer systems with representing times after 03:14:07 UTC on 19 January 2038; GPS week number rollover: time keeping integer rollover caused by the design of the Global Positioning System, which occurs every 19.6 years; 512k day: an event in 2014, involving a software limitation in network routers
