[$] 2038: only 21 years away

Sometimes it seems that things have gone relatively quiet on the year-2038front. But time keeps moving forward, and the point in early 2038 when32-bit time_t values can no longer represent times correctly isnow less than 21 years away. That may seem like a long time, but therelatively long life cycle of many embedded systems means that some systems deployed today will still be inservice when that deadline hits. One of the developers leading the effortto address this problem is Arnd Bergmann; at Linaro Connect 2017 he gave anupdate on where that work stands.
