...unfortunately, `zic' does not let you enter the transition time `24:00', meaning midnight at the end of the day; it complains `invalid time of day'. `zic' should probably be enhanced to allow 24:00, as that is often what the rules actually say -- Egypt is an example of this.... Here's a proposed patch for zic.c to explicitly allow 24:00 (or 24:00:00); certainly if it gets used in data files such as "africa", a comment about the potential need for downloading a new time zone compiler might be placed near the scene of the crime. --ado *** 7.94/zic.c Mon Sep 28 23:11:25 1998 --- 7.95/zic.c Mon Sep 28 23:11:26 1998 *************** *** 1,6 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.94"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 1,6 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.95"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 901,909 **** error(errstring); return 0; } ! if (hh < 0 || hh >= HOURSPERDAY || mm < 0 || mm >= MINSPERHOUR || ! ss < 0 || ss > SECSPERMIN) { error(errstring); return 0; } --- 901,910 ---- error(errstring); return 0; } ! if ((hh < 0 || hh >= HOURSPERDAY || mm < 0 || mm >= MINSPERHOUR || ! ss < 0 || ss > SECSPERMIN) && ! !(hh == HOURSPERDAY && mm == 0 && ss == 0)) { error(errstring); return 0; }
