TIMER: Multiple Actions

[AliGW]

Little crisis of confidence here - just need reassurance!

1. I have set a timer with a start and end date/time (start already in the past, end in the future).
2. I have added two page items that need to show during the period of the timer, so I shall set them as initially invisible - I learnt this when I first used such a timer.
3. I have a third page item that needs to show once the timer expires, so I am setting it to be hidden by the timer and will leave it as initially visible on the page. Is this correct? I think it should be, logically. Yes, I have tested it, and it seems to work, but just wondered if someone could just confirm my logic before I publish.

Thanks!
