Time compare methods? Automating changes based on times.

I want to control a Patch to make sure it only happens at a range of local times. I want something to only happen between 3:00 PM and 3:25 PM. One really hacky method I came up with is this:

If(DateDiff(Today(), Now(), Minutes) > 900 And DateDiff(Today(), Now(), Minutes) < 825,
Patch (...)
)

This would trigger when someone presses a button. However it would be great to have it auto trigger visible or not. I am worried this won't work since this won't be evaluated expcet on app start. Any suggestions?

Hi @BrianHFASPS

You could add a timer control to the app which would run on a schedule and then run your code logic

However this would only work when the App is running

I only need it to happen when app is running so that isn't an issue. I didn't think timers could work on external time but rather would only work on internal to app time. Can you have a timer trigger based on clock time?

Hi @BrianHFASPS

Your timer can start and end lets say every 5-10 secs
Every time timer ends
you can
If(DateDiff(Today(), Now(), Minutes) > 900 And DateDiff(Today(), Now(), Minutes) < 825, Patch (...) )
and then restarts the timer

Hi @BrianHFASPS ,

I suggest you try the App's OnStart property or Screen's OnVisible property.

The first one, it will trigger automatically when you run the app.

The second one, it will trigger automatically when you load this screen.

Set the App's OnStart property or Screen's OnVisible property to the formula that you listed.

Or you could try this formula:

If(TimeValue(Text(Now(),DateTimeFormat.LongTime))>=Time(15,0,0)&&
TimeValue(Text(Now(),DateTimeFormat.LongTime))<=Time(15,25,0),
Patch(...),
.....
)

Since I am doing an action during OnSelect or AppStart your formula works well. Thanks.
