Portugal to change timezone again (??)
by peter＠aldie.co.uk Feb. 29, 1996

Feb. 29, 1996

The following article appeared in uk.misc and a few other groups as part of a discussion of time matters. (It is surprising how much confusion there still is about the EU start/end dates.) >From: martin(a)ci.ua.pt (Martin Bruckmann) >Newsgroups: uk.misc,soc.culture.french,rec.travel.air,rec.travel.misc, > rec.travel.europe >Subject: Re: Time difference between Paris & London after clocks change >Date: 27 Feb 1996 15:35:53 GMT >Organization: Universidade de Aveiro, Portugal >Message-ID: <4gv8cp$atu(a)titan.ci.ua.pt> > >... >And, a novelty (or back to how it was before E.U.) : Portugal is >re-adopting its more natural time, i.e. the same as in the U.K. It is >still 1h delay compared to its solar time, but it's already better than >the E.U. imposed Central European Time, which forced little kids to >wake up very early to go to school in the total darkness in Winter... > >-- >All about Portuguese Internet Sites & People on http://sapo.ua.pt I asked for some more info by email and this was the result, quoted with permission: >From: Martin Bruckmann <martin(a)ua.pt> >To: peter(a)aldie.co.uk (Peter Ilieve) >Date: Thu, 29 Feb 1996 10:09:31 +0000 (PWT) > >> [my query] >> Is this true?

After a bit more clarification it seems that the new Portugese Prime Minister has got fed up with getting up in the dark in the Winter and has decided they won't put the clocks forward this March. I assume they will then put them back in October, reverting to GMT as they were before 1992. I am not an expert on Portugal and although Martin will undoubtedly know more than me I don't think he would consider himself a timezone expert, so best treat this as a warning for now. Does anyone know more? Peter Ilieve peter(a)aldie.co.uk

Timezone names for Greenland
by ohnielse＠fysik.dtu.dk Feb. 27, 1996

Feb. 27, 1996

Dear Sir, In your timezone data file for Europe you define: # -3:00 WGT+DST Western Greenland* # -2:00 MGT+DST Middle Greenland* # -1:00 EGT+DST Eastern Greenland* Zone America/Scoresbysund -1:29:00 - LMT 1916 Jul 28 -2:00 - MGT 1980 Apr 6 2:00 -2:00 M-Eur MGT%s 1981 Mar 29 -1:00 M-Eur EGT%s Zone America/Godthab -3:26:56 - LMT 1916 Jul 28 -3:00 - WGT 1980 Apr 6 2:00 -3:00 M-Eur WGT%s Zone America/Thule -4:35:08 - LMT 1916 Jul 28 -4:00 - AST The naming "America" is politically incorrect. Greenland is a part of Denmark, but has had home rule for 10 or 11 years. If anything, you would have to define the zone names as "Denmark/...." or perhaps "Greenland/....". Furthermore, the town names that you give are Danish names. Greenlanders would undoubtedly insist that the Greenland names be used, so perhaps better namings would be: America/Scoresbysund -> Greenland/Ittoqqortoormiit America/Godthab -> Greenland/Nuuk America/Thule -> Greenland/Dundas I don't know if the timezone names have been fixed by international convention, but the naming would appear controversial :-) With best regards, Dr. Ole H.

Bug in localtime.c
by Gibson_Roger/HEMEL_ENGINEERING_SERVERS＠uniplex.co.uk Feb. 23, 1996

Feb. 23, 1996

From: Roger Gibson (rxg(a)uniplex.co.uk) I have found a bug in 'localtime.c' for which I am sending a proposed fix. The problem occurs when 'mktime' is called with tm_mday <= 0, tm_mon > 1 and tm_year is a leap year or the year after a leap year. For such a case, the normalization is performed incorrectly, and yields a date which is one day out. The following example program demonstrates this: -------------------------------- #include <stdio.h> #include <time.h> int main() { struct tm tm; char buf[256]; memset(&tm, 0, sizeof tm); tm.tm_year = 96; /* 1996 */ tm.tm_mon = 2; /* March */ tm.tm_mday = 0; tm.tm_hour = 12; mktime(&tm); /* Should give Feb 29 */ strftime(buf, sizeof buf, "%C", &tm); printf("%s\n", buf); return 0; } -------------------------------- To deal with cases like this, the 'time2' function decrements the year, and adds the corresponding number of days to 'tm_mday'. The problem is that the number of days is taken to be that in the year after it has been decremented, whereas it is actually that in the year which contains the end of February which is spanned by the interval. It is necessary to take 'tm_mon' into account in determining this. The same problem occurs in the part of the code which deals with values of 'tm_mday' which exceed the number of days in a year. The version of 'time2' below contains my attempt to fix these problems. It seems to work, but I'd like to know if you concur. -------------------------------- Version information: static char elsieid[] = "@(#)localtime.c 7.44"; (Still present in version 7.55.) -------------------------------- static time_t time2(tmp, funcp, offset, okayp) struct tm * const tmp; void (* const funcp) P((const time_t*, long, struct tm*)); const long offset; int * const okayp; { register const struct state * sp; register int dir; register int bits; register int i, j ; register int saved_seconds; time_t newt; time_t t; struct tm yourtm, mytm; *okayp = FALSE; yourtm = *tmp; if (normalize_overflow(&yourtm.tm_hour, &yourtm.tm_min, MINSPERHOUR)) return WRONG; if (normalize_overflow(&yourtm.tm_mday, &yourtm.tm_hour, HOURSPERDAY)) return WRONG; if (normalize_overflow(&yourtm.tm_year, &yourtm.tm_mon, MONSPERYEAR)) return WRONG; /* ** Turn yourtm.tm_year into an actual year number for now. ** It is converted back to an offset from TM_YEAR_BASE later. */ if (increment_overflow(&yourtm.tm_year, TM_YEAR_BASE)) return WRONG; while (yourtm.tm_mday <= 0) { if (increment_overflow(&yourtm.tm_year, -1)) return WRONG; if (yourtm.tm_mon >= 2) yourtm.tm_mday += year_lengths[isleap(yourtm.tm_year + 1)]; else yourtm.tm_mday += year_lengths[isleap(yourtm.tm_year)]; } while (yourtm.tm_mday > DAYSPERLYEAR) { if (yourtm.tm_mon >= 2) yourtm.tm_mday -= year_lengths[isleap(yourtm.tm_year + 1)]; else yourtm.tm_mday -= year_lengths[isleap(yourtm.tm_year)]; if (increment_overflow(&yourtm.tm_year, 1)) return WRONG; } for ( ; ; ) { i = mon_lengths[isleap(yourtm.tm_year)][yourtm.tm_mon]; if (yourtm.tm_mday <= i) break; yourtm.tm_mday -= i; if (++yourtm.tm_mon >= MONSPERYEAR) { yourtm.tm_mon = 0; if (increment_overflow(&yourtm.tm_year, 1)) return WRONG; } } if (increment_overflow(&yourtm.tm_year, -TM_YEAR_BASE)) return WRONG; if (yourtm.tm_year + TM_YEAR_BASE < EPOCH_YEAR) { /* ** We can't set tm_sec to 0, because that might push the ** time below the minimum representable time. ** Set tm_sec to 59 instead. ** This assumes that the minimum representable time is ** not in the same minute that a leap second was deleted from, ** which is a safer assumption than using 58 would be. */ if (increment_overflow(&yourtm.tm_sec, 1 - SECSPERMIN)) return WRONG; saved_seconds = yourtm.tm_sec; yourtm.tm_sec = SECSPERMIN - 1; } else { saved_seconds = yourtm.tm_sec; yourtm.tm_sec = 0; } /* ** Calculate the number of magnitude bits in a time_t ** (this works regardless of whether time_t is ** signed or unsigned, though lint complains if unsigned). */ for (bits = 0, t = 1; t > 0; ++bits, t <<= 1) continue; /* ** If time_t is signed, then 0 is the median value, ** if time_t is unsigned, then 1 << bits is median. */ t = (t < 0) ? 0 : ((time_t) 1 << bits); for ( ; ; ) { (*funcp)(&t, offset, &mytm); dir = tmcomp(&mytm, &yourtm); if (dir != 0) { if (bits-- < 0) return WRONG; if (bits < 0) --t; else if (dir > 0) t -= (time_t) 1 << bits; else t += (time_t) 1 << bits; continue; } if (yourtm.tm_isdst < 0 || mytm.tm_isdst == yourtm.tm_isdst) break; /* ** Right time, wrong type. ** Hunt for right time, right type. ** It's okay to guess wrong since the guess ** gets checked. */ /* ** The (void *) casts are the benefit of SunOS 3.3 on Sun 2's. */ sp = (const struct state *) (((void *) funcp == (void *) localsub) ? lclptr : gmtptr); #ifdef ALL_STATE if (sp == NULL) return WRONG; #endif /* defined ALL_STATE */ for (i = 0; i < sp->typecnt; ++i) { if (sp->ttis[i].tt_isdst != yourtm.tm_isdst) continue; for (j = 0; j < sp->typecnt; ++j) { if (sp->ttis[j].tt_isdst == yourtm.tm_isdst) continue; newt = t + sp->ttis[j].tt_gmtoff - sp->ttis[i].tt_gmtoff; (*funcp)(&newt, offset, &mytm); if (tmcomp(&mytm, &yourtm) != 0) continue; if (mytm.tm_isdst != yourtm.tm_isdst) continue; /* ** We have a match. */ t = newt; goto label; } } return WRONG; } label: newt = t + saved_seconds; if ((newt < t) != (saved_seconds < 0)) return WRONG; t = newt; (*funcp)(&t, offset, tmp); *okayp = TRUE; return t; }

Timezones
by Ravi Narine Feb. 21, 1996

Feb. 21, 1996

Hi there, My name is Ravi Narine, and I am a software developer for Bell Sygma Inc. We are using the Timezone library that you have created. I am wondering is there a program that can take information (ex. city,country,province,state,area code or anything on that means) and return me the timezone that is in. Greatly appreciated Ravi Narine

In the GNU C library I use zic.c and zdump.c verbatim from tzcode96d, except for marking all the strings for user messages so they can be translated through message catalogs. Could these changes perhaps be merged so I don't have to re-modify each new version? It is quite simple and unobtrusive: put in private.h or someplace: #ifndef _ #define _(x) x #endif (in my system, _ will be defined as a macro that invokes the translation lookup). Here are the patches to zic.c and zdump.c to make their "messages" use _("messages"). Can I hope to get this merged into the tzcode distribution?

Hi Valery, > My man page on mktime() (Solaris2) clearly says that 'tm_year > of the tm structure must be for year 1970 or later.' This would seem to limit the usefulness of timezone rules prior to 1970 with respect to mktime(). Perhaps they did this for standards compliance? thanks, - Tom

This is, after all, exactly what mktime() does to determine is has the matching time_t. > Of course, we only need to check this > when the return of mktime() is -1 Exactly what I meant by "Call localtime() on the seemingly-in-error mktime() result."

Oops...point well taken! Would subtracting one from tm_sec (and looking for a return of -2) work? --ado
