-- Number of seconds to convert
local seconds = 1850

-- 1 day = 86400 s
-- 1 hour = 3600 s
-- 1 minute = 60 s

local days = math.floor(seconds / 86400)
local hours = math.floor((seconds - days * 86400) / 3600)
local minutes = math.floor((seconds - days * 86400 - hours * 3600) / 60)
      seconds = math.floor(seconds - days * 86400 - hours * 3600 - minutes * 60)

print(days .. ' J ' .. hours .. ' H ' .. minutes .. ' MINS ' .. seconds .. ' S ')
