Merge World Clock and Date/Time plugins

[jleclanche]

Good cleanup now that we no longer support qt < 5.3

[jleclanche]

@kuzmas would you like to take this?

[kuzmas]

@jleclanche ok

[jleclanche]

@kuzmas Targeting a december release if possible (pre-christmas). I'm tentatively leaving this on the 0.9 milestone.

@kuzmas you can push your current work to a branch, if you want help.

'Wordlclock' is friendlier now, 'clock' is turned off by default.

I have some ideas for future:

1. Add formats 'H:mm AP'/'HH:mm' and 'H:mm:ss AP'/'HH:mm:ss'. For that we need to detect whether current locale uses AM/PM or not.
2. Add special case for 'local timezone' (currently if no timezones specified in the list - it shows local timezone, but it would be nice to have it as an item in a list as well)

@jleclanche And as to non-constant width: we can make sure font in theme is monospaced, otherwise we can calculate the widest possible combination of datetime values and use its width as fixed (it can potentially take long to iterate through all combinations, since datetime format can contain anything)

Close this issue? All in favour?

@kuzmas I haven't tested yet but last I checked. world clock needed some severe improvements in order to be as good as clock; namely in the configuration.

[jleclanche]

BTW, if the two are considered merged, please remove the "clock" plugin and replace it by the worldclock plugin. Will need to test upgrade paths from 0.8 too.

[kuzmas]

@jleclanche well, technically they aren't merged, it's just worldclock covers all functionality of clock plus a lot more.

And I agree, configuration is a bit complicated. I'm open to suggestions.

[jleclanche]

@kuzmas ill do a UX pass on it when I get time.

Would it be possible to show the list with all timezones chosen under the calendar (like eg. gsimplecal)?

[kuzmas]

@pepa65 I'm not sure what you mean. Worldclock has the list of all timezones in configuration. It can show time of all selected timezones, it can show the calendar and the calendar (current day and the first day of the week) depends on the shown timezone.
