The end of an Era – changing every single instance of a 32-bit time_t in Linux
Meanwhile, the unsigned 32-bit count of seconds (also) since 1970 used in pcap output from tcpdump, and used universally throughout the financial industry with no hint of a move away from it, will not roll over until 2106. If they are still in use then, code will interpret small values as implying a time after 2106, rather than as an ancient historical time before 2000.<p>It is hard to know why anybody thought it so urgent to go to 64-bit seconds counters for internal use in the kernel.
