Implementing "Clock" In Lualine

[harrisoncramer]

Hello All,

First off, thank you for the amazing plugin. It's exactly what I needed from a status line plugin.

I'm curious, is it possible to implement a function that will update? I'm currently using this Lua expression to get the current time:

os.date("%I:%M:%S", os.time())

However, this only updates when I type (which is odd) How might you implement this so that it's updated every second? Thanks again!

Lualine itself doesn't trigger any statusline redraw. Instead when
neovim tries to redraw statusline lualine provides what to draw.
Neovim only redraws statusline on certain events (as optimization). If you don't like the default
behavior, you can trigger statusline redraw with :redrawstatus You can set a timer to update statusline every
1000ms like following this.

if _G.Statusline_timer == nil then
  _G.Statusline_timer = vim.loop.new_timer()
else
  _G.Statusline_timer:stop()
end
_G.Statusline_timer:start(0,             -- never timeout
                          1000,          -- repeat every 1000 ms
                          vim.schedule_wrap(function() -- updater function
                                              vim.api.nvim_command('redrawstatus')
                                            end))

Can this be used to display UTC time? I tend to need UTC to schedule cronjobs in servers

@dmartzol prepend the time pattern with ! to see UTC time regardless of your timezone. Example

os.date('!%I:%M:%S')

If ! is not given it'll show you time of your timezone.

This is awesome, thank you!

why do I get the time in UTC on the contrary? but I need localtime...
'os.date("%H:%M")'

[DartMitai]

and so in order to get a normal time, I was prompted with this option
'os.date("!%H:%M", os.time() + (60 * 60 * 5))'
however, why he always output UTC remains unclear...
