So, now that the WoW API allows us to see time remaining until our PvP flag drops, I of course wanted it in PitBull... Adding it of course simply meant adding a DogTag for it, and DogTags are really well written so adding the new tag proved pretty easy.

Here's my ticket with the code:
http://www.wowace.com/projects/libdogtag-unit-3-0/tickets/6-pvp-remaining-timer-for-dogtags-pitbull/

And here's the code itself:

in Status.lua add:

DogTag:AddTag("Unit", "PVPRemaining", {
    code = function(unit)
        if unit == 'player' and IsPVPTimerRunning() then
            local t = GetPVPTimer()/1000
            if(t < 1) then
                return nil
            else
                return t
            end
        else
            return nil
        end
    end,
    arg = {
        'unit', 'string;undef', 'player'
    },
    ret = "number;nil",
    events = "PVPRemaining#$unit",
    doc = L["Return the time remaining until PVP flag expires"],
    example = ('[PVPRemaining] => "110"; [PVPRemaining:FormatDuration] => "1:50"'),
    category = L["Status"]
})

And I added this to DogTag:AddTimerHandler:

    
    if IsPVPTimerRunning() then
        DogTag:FireEvent("PVPRemaining", 'player')
    end

Then I just added a text field with this DogTag in PitBull:

[PVPRemaining:FormatDuration]

Works great for me, I attached it the top right of my Player frame, inside, which puts it just next to the PvP Icon:

Nice job!

And I added this to DogTag:AddTimerHandler:

    
    if IsPVPTimerRunning() then
        DogTag:FireEvent("PVPRemaining", 'player')
    end

Could you, please, explain this part more thoroughly if it's not too much trouble?

Yeah, in Status.lua there is currently a method that begins like this:

DogTag:AddTimerHandler("Unit", function(currentTime, num)
	if first then
		first = false
		PARTY_MEMBERS_CHANGED()
	end
	
	for guid in pairs(offlineTimes) do
		for unit in DogTag_Unit.IterateUnitsWithGUID(guid) do
			DogTag:FireEvent("OfflineDuration", unit)
		end
	end

Simply add the code like this:

DogTag:AddTimerHandler("Unit", function(currentTime, num)
	if first then
		first = false
		PARTY_MEMBERS_CHANGED()
	end
	
	if IsPVPTimerRunning() then
		DogTag:FireEvent("PVPRemaining", 'player')
	end
	
	for guid in pairs(offlineTimes) do
		for unit in DogTag_Unit.IterateUnitsWithGUID(guid) do
			DogTag:FireEvent("OfflineDuration", unit)
		end
	end

This code is used to determine when Dogtags/Pitbull refreshes the count. There is no normal event associated with the count decreasing, so like other counters, I fake the event. This only applies to 'player' though, so I can simply fire it for them, no need to fire it for every unit.
