World clock in awesome

Awesome systray

For displaying multiple clock in awesome with different timezones we need to create new clock widgets, this post is based on awesome 4.2, you will need to create a new widgets in ~./config/awesome with the following code: utc.lua

It has just two differences with the original textclock.lua widget, here the diff output from these two files:

<     format = format or " UTC:  %H:%M || "
>     format = format or " %d local: %H:%M "
<    timezone = timezone or TimeZone.new("Z")
>    timezone = timezone and TimeZone.new(timezone) or TimeZone.new_local()

I'm not a programmer, but I read the programmer Documentation and modified the code accordingly, I only was able to understand that the parameters after the OR operand was true and I don't know why, but my code works.

Its important to notice that you have to specify the timezone name in the format variable in order to show the clock's name, check the bold text in the diff output above.

The most important thing to do is to replace the Z in the TimeZone.new("Z") function, Z is the UTC timezone, in the case of Argentina the timezone would be: TimeZone.new("America/Buenos_Aires")

Then edit your ~/.config/rc.lua file and search for this string:

mytextclock = wibox.widget.textclock()

In order to use the widget we have to pass the function into a variable, so if we have the Argentina and UTC clocks besides the local one, it will look like this:

mytextclock2 = textclock2()
utc= utc()
mytextclock = wibox.widget.textclock()

Finally search for the widgets wibox session and add the declared variables there:

-- Add widgets to the wibox
    s.mywibox:setup {
        layout = wibox.layout.align.horizontal,
        { -- Left widgets
            layout = wibox.layout.fixed.horizontal,
        s.mytasklist, -- Middle widget
        { -- Right widgets
            layout = wibox.layout.fixed.horizontal,
