Os.time returns what system time?

local delta = timeValue - os.time()
local seconds = math.floor(delta) % 60
local minutes = math.floor(delta / 60) % 60
local hours = math.floor(delta / 60 / 60) % 60
local days = math.floor(delta / 60 / 60 / 24) % 60
local prettyString = string.format("%d days and %02d:%02d:%02d left!", days, hours, minutes, seconds)

print(prettyString)

It seems like there was an issue with hours, it started giving the correct time after applying this:

local hours = math.floor(delta / 60 / 60) % 24
