Date et heure en lua : formatage pour Domoticz

--J'ai vu cette technique sur https://www.lua.org/pil/22.1.html
year 	= tonumber(os.date("%Y"));
month 	= tonumber(os.date("%m"));
day 	= tonumber(os.date("%d"));
hour 	= tonumber(os.date("%H"));
minutes 	= tonumber(os.date("%M"));
seconds 	= tonumber(os.date("%S"));

if (string.len(month) == 1) then month = "0" .. month end
if (string.len(day) == 1) then day = "0" .. day end
if (string.len(hour) == 1) then hour = "0" .. hour end
if (string.len(minutes) == 1) then minutes = "0" .. minutes end
if (string.len(seconds) == 1) then seconds = "0" .. seconds end

logtime = year .. month  .. day  .. " " .. hour  .. minutes  ..  seconds
