Antoine Leca wrote: Coca is the brand name under which Coke is know here in (Latin) Europe. Coca also happen to be the name of a traditional cake made in the region of my wife. Should the cake shop vendors change the name of the product . . . ? I see two big differences between the above example and the suggestion that the new API should be called "Timex". First, the traditional cake is a very different item from the beverage, so there is unlikely to be any confusion in the average person's mind as to whether the "coca" cake has anything at all to do with "Coca" cola. Second, the name "coca", as a traditional cake, was around long before "Coca" came into use as a beverage trademark. In North America, at least, my understanding is that these issues are considered significant in trademark law. for example, back in the days when "UNIX" was a trademark at various times of Bell Labs, AT&T, and others, I recall hearing it said that someone could (if they so desired) probably market "UNIX" brand ice cream (!) without infringing the trade- mark -- but using the term "UNIX" to identify any computer-related item (even something other than an OS) most likely wouldn't fly. I would view the "TIMEX" proposal in the same way. Using "TIMEX", "Timex", or "timex_" to identify anything having any relationship at all to time would, I assume, almost certainly provoke an unfriendly response by Timex Corporation's legal staff. First, Timex Corp. has already been venturing somewhat into the computer field with their "Data Link" line of watches with builtin personal information managers. Hence, they would probably be sensitive to =any= computer-related use of the "Timex" name by anyone but themselves. Second, even if the new API were obviously not going to compete for Timex's market share, they would surely put up a fight on principle, lest their precious registered trademark end up falling into common generic use (as has already happened with Kleenex, Xerox, and Coke). Just my (non-lawyer) opinion, of course. Rich Wales richw(a)webcom.com http://www.webcom.com/richw/ *DISCLAIMER: I am not a lawyer.

As an addendum to my earlier note, I was informed that "TIMEX" or "Timex" is likely a registered trademark of a watch manufacturer. Consequnetly to avoid difficulties, I suggest that we use the term "timex_" as the reference. To this we can then add "format" "resolve", etc. Another alternative would be to use "timx" as the term Regards - Jake Knoppers <mpereira(a)istar.ca>

I think we need to poll the voting members to determine whether anybody insists on having struct tmx in C9x. If not, since there has been some formal objection to it, backing out the struct tmx related changes seems like an appropriate way to respond to (adverse) public comment. Personally I'd rather see a completely satisfactory technical solution than layering on a still-not-satisfactory solution. Since I doubt the former can be done within the C9x schedule, leaving <time.h> pretty much the way it was in C89 seems proper.

I would recommend using the term "timex". It is a invented term, a.k.a. coined term or neoligism, to which can be attached the apprpriate definition as well as a note at the end of such defintion of " Formerly known as xtime". "Time" as word is used with multiple meanings and its use can quickly become confusing and inadvertently may have unforeseen results. Having the x precede the _resolves the ambiguity resulting from the x after _ . Trust that this is of some help - Jake Knoppers P.S. For questions of this nature you may find ISO 2788 - Guidelines for the establishment and development of monoligual thesauri and ISO 5964 Guidelines for the establishment and development of multilingual thesauri to be of some help. They include rules for the establishment of terms and controlled vocabularies. If I can be of help elsewhere, SVP let me know.

About the changes in the counting of time in The Republic of Latvia
by Liene Kanepe Sept. 17, 1998

Sept. 17, 1998

I have tried to collect information about all changes in the counting of time in Latvia. I asked about this matter Scientific Secretary of the Institute of Astronomy of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the correct data in juridical acts and I found some juridical documents about changes in the counting of time in Latvia from 1981: - Act No.35 of the Council of Ministers of Latvian SSR of 22 January,1981 on the order of counting of time on the territory of Latvian SSR; - Act No.592 of the Council of Ministers of Latvian SSR of 24 September, 1984 on changes in the Act No.35 of the Council of Ministers of Latvian SSR of 22 January,1981 on the order of counting of time on the territory of Latvian SSR; - Act No.81 of the Council of Ministers of Latvian SSR of 22 March,1989 on the changes of counting of time on the territory of Latvian SSR; - Regulations of the Cabinet of Ministers of the Republic of Latvia of 21 January, 1997 on transition to Summer time. Act No.35 of the Council of Ministers of Latvian SSR of 22 January,1981 on the order of counting of time on the territory of Latvian SSR according to the Act No. 925 of the Council of Ministers of USSR of 24 October, 1980 established such order of counting of time: all year round the time of 2nd time zona + 1 hour, in addition turning the hands of the clock 1 hour forward on the 1st April at 0.00 o'clock (GMT 31st March 21:00) and 1 hour backward on the 1st October at 0.00 o'clock (GMT 30 September 20:00). Act No.592 of the Council of Ministers of Latvian SSR of 24 September, 1984 on changes in the Act No.35 of the Council of Ministers of Latvian SSR of 22 January,1981 on the order of counting of time on the territory of Latvian SSR according to the Act No. 967 of the Council of Ministers of USSR of 13 September, 1984 established such order of counting of time on the territory of Latvian SSR: all year round the time of 2nd time zona + 1 hour, in addition turning the hands of the clock 1 hour forward on the last Sunday of March at 02.00 o'clock (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of September at 03.00 o'clock (GMT 23:00 on the previous day). Act No.81 of the Council of Ministers of Latvian SSR of 22 March,1989 on the changes of counting of time on the territory of Latvian SSR according to the Act No. 227 of the Council of Ministers of USSR of 14 March, 1989 established such order of counting of time: since the last Sunday of March, 1989 in Lithuanian SSR, Latvian SSR, Estonian SSR and Kaliningrad region of Russian Federation all year round the time of 2nd time zona (Moscow time minus one hour). On the territory of Latvia transition to summer time is performed on the last Sunday of March at 02.00 o'clock (GMT 0:00), turning the hands of the clock 1 hour forward . The end of daylight saving time is performed on the last Sunday of September at 03.00 o'clock (GMT 0:00), turning the hands of the clock 1 hour backward. Exception is 26 March of 1989, when we must not turn the hands of the clock. According the Act No.81 of the Council of Ministers of Latvian SSR of 22 March,1989 Act No.35 of the Council of Ministers of Latvian SSR of 22 January,1981 and Act No.592 of the Council of Ministers of Latvian SSR of 24 September, 1984 lost validity. In 1996, when the European Union changed the end of daylight savings time to the last Sunday of October, Latvia had not changed the end of daylight savings time. And this is pardonable for Latvia, because it is not a member - state of the European Union. Latvia changed the end of daylight savings time to the last Sunday of October only in 1997. Then were accepted the Regulations of the Cabinet of Ministers of the Republic of Latvia of 21 January, 1997 on transition to Summer time. According these regulations Act No.81 of the Council of Ministers of Latvian SSR of 22 March,1989 lost validity and was established the same order of daylight savings time settings as in the States of the European Union. From the 1997 Latvia changes from Winter time to Summer time on the last Sunday of March at 3 a.m.(Latvian time) or 1.00 GMT. It changes from Summer time to Winter time on the last Sunday of October at 4 a.m. (Latvian time) or 1 GMT.

the territory of Latvia (13 October, 1944 for Riga) until the 31st March, 1981, GMT 21:00 the time offset from GMT for Latvia was 3 hours. It seems, that before 13 October, 1944 it was 2 hours, except the period, when Latvia was incorporated in the Soviet Union (approximatly from 05 August, 1940 until 21 June, 1941) and the period, when during the Second World War Latvia was occupied by Germany. If I find the more correct data about the time offset from GMT for Latvia in the period before 1944, I will mail You. With the best regards from The Republic of Latvia, Riga Liene Kanepe

There is an old tradition of language design that the language and its libraries strongly avoid using identifiers starting with the letter "x" --- a desperate application writer can then blithely prepenend an "x" to all its first-choice identifiers and be safe.

I also think it may be too late for incorporating huge changes in the time functions, as Clive lastly proposed. I am also reluctant to introduce such changes *after* the FCD stage (correct me if I am wrong, but I see it as contrary to what a FCD should be, and it may raise virulent formal objections later, at FDIS stage). > Instead, I propose that <time.h>'s problems be fixed by removing the > struct-tmx-related changes to <time.h>, reverting to the the current > ISO C standard (C89); we can then come up with a better <time.h> for > the next standard (C0x). Another way may be to back up to C90 state, as Paul proposed, and then to publish the output of the experts working in this area in the form of an amendment to the standard, to be published around 2002-2003 (to be compared with 2010 for C0X).
