Question on time picker

[404synt...@gmail.com]

I am currently working on an attendance app that requires recording time on a 1-minute time interval, but the built-in timer in code name one only have an interval of 5 minutes. I was trying to use string picker instead, yet the way that two of them (hour and minute) are on different lines really upsets me. I am wondering if there's a better way to customize the time picker or go with a different route to fix the problem. Thank you!
