Time to switch from "false" to "true"!

[phongvucba]

Hi everybody ! I have a little trouble? Hope everybody help please:

-My address changes from "false" to "true", it needs to be 1.254s. I see it in the "Update at" section. How do I know that time? I want to do something with this "1,254s".

Thank so much everybody !

delta variable will have the time between FALSE and TRUE values in seconds.

Code:

value = event.getvalue()

if value then
  prevtime = storage.get('prevtime')
  
  if prevtime then
    storage.delete('prevtime')
    delta = os.udifftime(unpack(prevtime))
    log(delta)
  end
else
  storage.set('prevtime', { os.microtime() })
end
