different value throughout the day

[admin]

You can convert current time to a number of minutes passed since 0:00 and use it in your calculations. Use this example to check if current time is between 5:30 and 10:00

Code:

function tominutes(h, m)
  return h * 60 + m
end

now = os.date('*t')
mins = tominutes(now.hour, now.min)

if mins >= tominutes(5, 30) and mins <= tominutes(10, 0) then
  -- do something here
end
