[$] Approaching the kernel year-2038 end game

In January 2038, the 32-bit time_t value used on many Unix-likesystems will run out of bits and be unable to represent the current time.This may seem like a distant problem, but, as Tom Scott recently observed,the year-2038 apocalypse is now closer to the present than the year-2000problem. The fact that systems being deployed now will still be operatingin 2038 adds urgency to the issue as well. The good news is that work has been underway for years to prepareLinux for this date, so there should be no need to call developers out ofretirement in 2037 in a last-minute panic. Some of the final steps in thistransition for the core kernel have been posted, and seem likely to bemerged for 5.1.
