fibonacci time zones

[Plumplum]

Hello

Does anyone know of a video on how to set up Fibonacci Time Zones in MT5? 

I've read this 

https://www.metatrader5.com/en/mobile-trading/iphone/help/chart/objects/fibo/fibo_timezones

1. Iam still unclear what to put into the Parameters next to the date and time - starting point and ending point (where you see all zeros in the attached screen shot from my phone)...I thought once you choose the date and time, the levels on the right should auto populate (based on the selected date and time)? 

2. Is there a way to selected the start and end point on the iPhone screen by zooming and pressing down on a point - will the parameters auto populate?

So confused...Thank you!
