Convert number of seconds to a TTS friendly format

[etron]

I use the code below to announce the values of my Elk M1 counters, which are used as timers.



local function FormatForTTS(sSeconds)
local nSeconds = tonumber(sSeconds)
local sTTS = ""
if nSeconds < 60 then
return "timer has expired"
else
nHours = math.floor(nSeconds/3600)

if nHours > 1 then
wHours = nHours.." hours"
end
if nHours == 1 then
wHours = "1 hour"
end
if nHours == 0 then
wHours = ""
end

nMins = math.floor(nSeconds/60 - (nHours*60));

if nMins > 1 then
wMins = nMins.." minutes"
end
if nMins == 1 then
wMins = "1 minute"
end
if nMins == 0 then
wMins = ""
end

nSecs = math.floor(nSeconds - nHours*3600 - nMins *60);

if nSecs > 1 then
wSecs = nSecs.." seconds"
end
if nSecs == 1 then
wSecs = "1 second"
end
if nSecs == 0 then
wSecs = ""
end

-- putting it all together now
if nHours > 0 then
sTTS = sTTS .. wHours
if nMins > 0 then
sTTS = sTTS .. " and "
end
end

if nMins > 0 then
sTTS = sTTS .. wMins
if nSecs > 0 then
sTTS = sTTS .. " and "
end
end

if nSecs > 0 then
sTTS = sTTS .. wSecs
end

return "Time remaining: " .. sTTS
end
end
