Hi @gregersen79
Thank you for reporting this issue.
We are going to try replicate this case on our end. Let me know if you can send us a sample project or playground link so we can reproduce the issue.

Hi @Ross-Olivares I don't have a sample project at the moment, but let me know if you need it. What I try to do is simply to set the minuteInterval property on the TimePicker object, and I have also tried setting it on the native object

timePickerViewObj.ios.minuteInterval = 15;

Also setting the minHour and minMinute properties seems to have no effect.

@gregersen79 I tested and it seems to be working on my end, can you try this application
Let me know how it goes.

@Ross-Olivares Unfortunately I can't run the application you in your link, I had to migrate it to Nativescript 7 and I get an error when trying to do this (something about "Not in Git repo"). The two main differences on our projects is yours is Typescript and I'm using Javascript, your targeting {N}6.5 and I'm targeting {N}7. Don't know if this could mean something.
But I have made a very simple sample project to reproduce it. I just created a new project and added a Timepicker to xml

<TimePicker minuteInterval="15" minHour="8"/>

And still I was able to select every minute, and go back hours below 8.
Let me know if you would like me to send this sample project.

@gregersen79 Yes send me your sample project.
