From 5b521f3c4f8da9d35e865fb9daa7a51e4fa00adb Mon Sep 17 00:00:00 2001 From: dillon Date: Sun, 28 Oct 2001 19:54:49 +0000 Subject: Add routines to convert time_t to/from fixed-bit fields. These routines serve two purposes: (1) so we can maintain backwards compatibility with protocols (rwhod, dump, etc...) that either assume time_t is 32 bits or assume sizeof(time_t) == sizeof(int), or make other similar assumptions. (2) To tag such routines (by the presence of these calls) for future cleanup/extension work. The 32->64 routine, time32_to_time() (when time_t is 64 bits, that is), is defined specifically to implement temporal locality to properly set the msb bits of a 64 bit time_t quantity, using the 50 year rule. The locality code has not been implemented yet (and doesn't need to be for a while), but that is the intent. This will allow us to maintain backwards protocol compatibility past 2038. These routines are intended to be platform and time_t agnostic.
