Why 2038 matters

Classic Unix timestamps are stored as a 32-bit signed integer counting seconds since January 1, 1970 — and that number runs out on January 19, 2038. Systems still using 32-bit timestamps will wrap around to a negative number and effectively jump back to 1901. Most modern systems have already moved to 64-bit timestamps, which push the problem out roughly 292 billion years, but it's worth knowing why “the 2038 problem” comes up if you work with older systems or embedded devices.
