Merge lp:~stellarium/stellarium/tz into lp:stellarium

[Alexander Wolf]

Added time zone support

[Alexander Wolf (alexwolf)]

I've removed Time Zone plugin but maybe I should restore him and use him for management really custom rules for time zone and DST?

review: Needs Information

[gzotti (georg-zotti)]

I very much welcome a thorough re-work on the timezone issues, the many bug and wishlist items speak for themselves.

I had no time for a thorough test so far. Do you want to merge now and run public testing for a few weeks on the new trunk betas (and of course fix a few rounds in trunk), or have some testers on this branch and merge only when all is done? Can you publish betas from this branch?

I think some extra TZ settings options can be built into the main program's location panel. (This can become a bit larger. Also the map is very small on FullHD and higher-resolution screens.) There is no use to have a plugin when you must have it activated anyway for really basic operations. The configuration panel is more easily reached in this way.

Some things that can hopefully solved with IANA's TZ database:
DST rules for "Continent/City" timezones. In various countries, DST was introduced at some point in the 20th century. (e.g. WW1, WW2, energy crisis in the 1970s). It would be great if all times can be produced here.
Timezones were introduced around 1886, but not everywhere. Some standardisations were available previously (e.g. Railway time). The current 1886 limit may need a second thought.

Some useful options:
Have a tick (default=active) "System Defaults". This uses time zone of configured location.
Use system settings, but disable DST.
Set timezone as UT offset (15 minute steps)
Use Local Mean Solar Time. This should be default until 1885 (or we find some other meaningful date?).
Use Local True Solar Time (i.e. also add Equation of Time!) This may be useful for historical research. LTST use should be marked somehow in the bottom bar.

In any case, UT+HH:MM should be visible in the bottom toolbar like it is now. Maybe print TZ name or "LMST" in addition?

Updates and improvements

[Alexander Wolf (alexwolf)]

I prefer merge it in trunk and allow to testing it by wide circle of users.

I've added LTST also and allows to enabling/disabling DST.

Adding of full list of all exists time zones is... difficult, because in this case we should implement own tool to manage all them.

Please check last changes.

Another cosmetic fix - let's hide combobox for TZ when we use time zones from locations

[gzotti (georg-zotti)]

LTST is great! However, it should be marked in the bottom status line, else just UT+HH:MM looks like LMST. ALso, the last change, hiding the combobox, is more confusing than helpful. I suggest the timezone combo should be visible (so that you can see what has been found for the city), but unclickable when time from location is active.

When I switch from LMST back to zone time (or activate default) it seems the LMST longitude offset is not set back, or even all auto-zone lookup fails, it seems to keep LMST offset when I select a city.

Disabling DST seems OK for now.

Please use tooltip with info for LMST/LTST and current time zone name. Or you meant that I should remove UTC+XX:XX data and use LMST/LTST instead?

I'll check switching from LMST - it should be work correct.

[Alexander Wolf (alexwolf)]

I can introduce additional UTC+XX:XX time zones with 15-min. step also - should be the range UTC-12:00 -- UTC+12:00?

[gzotti (georg-zotti)]

Don't forget that tooltips sometimes don't work. Win7/NVidia OpenGL frequently just has no tooltips. (This was my default until recently!)

Optimal would be to see "UT+HH:MM", "UT+HH:MM (LMST)" or "UT+HH:MM (LTST)"

[gzotti (georg-zotti)]

According to https://en.wikipedia.org/wiki/Time_zone#Offsets_from_UTC
this should even go up to UT+14:00.
Not sure: Half-hour offsets seem frequent, but there are only very few 15-min offsets (Nepal, Australia). Make all, or only the particular actually existing zones? Can you filter the existing zone offsets from the IANA list?

[Alexander Wolf (alexwolf)]

OK for the tooltip problem.

For time zones in format UTC+HH:MM - we are have them in this format already. Please see bottom of the list.

[gzotti (georg-zotti)]

Ah yes. OK, Zone list seems complete.

When I am in "Custom zone" mode and select a zone, then disable custom zone, the combo is hidden and correct zone is used. When I then select a neighbour town, it goes back to some other zone. Not even the previously selected!

Example: I set Vienna, but custom zone America/Indianapolis, deselected custom zone (came back to Europe/Vienna), selected some location in Poland, and we were in zone America/Bogota. I see the zone offset in the status bar and zone name in the tooltip, OK. But custom timezone is disabled, so we should correctly be in Europe/Warsaw! I would prefer to see the combobox, just disabled, for reference, and of course correct zone lookup when custom time zone is disabled.

Cosmetic fix

[Alexander Wolf (alexwolf)]

Please check it again.

[gzotti (georg-zotti)]

New observations: Immediately after start, tooltip timezone string is not set under some circumstances. Yes, when ini:localisation:time_zone is missing because it is set to default.

I call the location panel. custom timezone disabled, DST enabled. Displayed time zone: Local Mean Solar Time. This is wrong. It could be UTC+2:00?
Still my time is correctly displayed as UTC+2:00, not LMST.
When I click on my city in the list, all is OK.
This may have to do with an "unnamed" location (just long/Lat). My startup location is not in the site list. Maybe better always store time_zone?

The "Bogota" problem is however solved. ... No, now sometimes it's the other way! Custom tz disabled, I select a city, and TZ goes to previously selected Europe/Vienna. I have to enable custom zone and disable it again to switch to the correct one. I have not found a pattern yet to trigger this confusing behaviour.

When I click a location on the map, accurate country-based timezone is not found automatically, of course. But you could simply suggest a UT+XX zone from Longitude/15, this should fit a first guess.

I have auto-location from IP query disabled. Does this also deliver a timezone?

Maybe add the longitude time offset (LMST) and equation of time value (LTST) in the tooltip? My preference would be "UT+HH:MM", "UT+HH:MM (LMST)" or "UT+HH:MM (LTST)" in the time string directly (avoid problems with tooltips not working).

[Alexander Wolf (alexwolf)]

Sorry, but your location was defined by user and he don't have info about time zone - LMST is good solution for guessing here. It's correct behaviour.

>My startup location is not in the site list. Maybe better always store time_zone?

No, because this will cause the old behaviour but with new mistakes.

> I have auto-location from IP query disabled. Does this also deliver a timezone?

Yes.

> My preference would be "UT+HH:MM", "UT+HH:MM (LMST)" or "UT+HH:MM (LTST)"

Please give use case, when it may be useful.

I expect tons of misunderstanding. But this is what user testing is all about, let's see then how useful it feels after a few weeks.

Where is it not useful? This mode is mostly for users with advanced requirements (but not necessarily expert astronomers, but maybe historians of science) who understand the difference but e.g. want to be sure it is computed correctly, they don't make a mistake in their thoughts, or want to explain the difference to others.

[Alexander Wolf (alexwolf)]

Well, let's try public testing :)

[gzotti (georg-zotti)]

When I go back to my stored location, "Use custom timezone" is disabled, but the correct TZ shown.
After restarting Stellarium, you are using correct UT+2, but location panel indicates LMST.
This is confusing. I had stored a location with custom TZ Europe/Vienna plus active DST (resulting in UTC+2). However, after reverting to default location the previously stored TZ is not again stored in config.ini, so I assume the UTC+2 comes from system settings. Still, the location panel shows LMST.

Maybe you must remember custom time zone from startup to be able to reset properly to startup location/TZ.

LMST/LTST display is fine now!

OK, I expect some user questions/complaints about some inconsistent behaviour which I described until this is fixed, but else I agree this is (going to be) much better user experience than the previous plugin-based TZ handling which required program restart. So this is the way to proceed, and yes for public testing!
