Format a number to needed format

[HNB]

Hello
I would like to get time to this format h:m : 13:57

When i use Hours from DateNow it is working when i have more than 10 hours and more than 10 min.

But when i have 03:07 i am get getting 3:7

How to force adding 0 before unit number?

Thanks in advance
