[Bug 185190] Re: City (Pittsburgh) Associated w/ Wrong Timezone
This certainly coincides with what I'm seeing. St Petersburg, Fl ->
Houston, Tx = 787 miles. Clearly less than the 835 miles to Washington,
DC.
Could something like ensuring the difference in longitude does not
exceed a certain value (presumably somewhere in the 7.5 degree mark)
help reduce (or even eliminate) this problem?
I.e. the code would read something like this (WARNING - untested...
quite possibly not the correct syntax!):
for (l = zones; l; l = l->next) {
ClockZoneInfo *info = l->data;
clock_zoneinfo_get_coords (info, &zlat, &zlon);
d = distance (lat, lon, zlat*M_PI/180.0,
zlon*M_PI/180.0);
if (d < dist && abs(lon - zlon*M_PI/180.0) <= 7.5) {
best = info;
dist = d;
}
}

[Bug 185190] Re: City (Pittsburgh) Associated w/ Wrong Timezone
Yes, I've confirmed with a look at the code that there's no timezone-
mapping database. The coordinates are not "parsed incorrectly",
however; the trouble is this:
for (l = zones; l; l = l->next) {
ClockZoneInfo *info = l->data;
clock_zoneinfo_get_coords (info, &zlat, &zlon);
d = distance (lat, lon, zlat*M_PI/180.0,
zlon*M_PI/180.0);
if (d < dist) {
best = info;
dist = d;
}
}
The default timezone is calculated using nothing more than the raw
distance to the cities after which the timezones are named. This is
nonsense, this is obviously not how timezones are divided.
It would be far better for the location selector to not provide a
default timezone at all, rather than configuring a wrong one.
This may become a non-issue if bug #199644 is fixed.

[Bug 185190] Re: City (Pittsburgh) Associated w/ Wrong Timezone
There is no database used for timezone mapping. There is a file called Locations.xml in libgweather that gives coordinates (among other things) for all locations. Somewhere, the coordinates are parsed incorrectly and mapped to the wrong timezones. -- City (Pittsburgh) Associated w/ Wrong Timezone https://bugs.launchpad.net/bugs/185190 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 185190] Re: City (Pittsburgh) Associated w/ Wrong Timezone
Various bugs have been marked as duplicates of this one, but each refers to different cities. Documenting here the cities whose timezones are set incorrectly: Eugene, OR (should be America/Los_Angeles, is set to America/Boise) Portland, OR (should be America/Los_Angeles, is set to America/Vancouver) Bombay/Santacrus (Asia/Karachi -> Asia/Calcutta) Houston, TX (America/Monterrey -> America/Chicago) Nashville, TN (America/Kentucky/Monticello -> America/Chicago) St. Petersburg, Russia (Europe/Helsinki -> Europe/Moscow) This may indicate multiple buggy entries in a database used for timezone mapping - or, it might suggest that the timezones are wrongly chosen based on which city is closest to the indicated city? -- City (Pittsburgh) Associated w/ Wrong Timezone https://bugs.launchpad.net/bugs/185190 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Thanks. I examined the XML file and nothing is out of order there. The latitude/longitude, IWIN, forecast, and radar codes are all correct. It seems that the problem is in the gnome-panel package, and not libgweather or gnome-applets. I do not see where the time zone is generated from. If it is parsed from the coordinates, then they issue may lie in that algorithm. -- City (Pittsburgh) Associated w/ Wrong Timezone https://bugs.launchpad.net/bugs/185190 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug contact for gnome-panel in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
