Issue with datetimepicker in datetime mode and minuteInterval

Hi everyone,

I’ve encountered an issue with the datetimepicker when it’s set in datetime mode and a minuteInterval is used (for example, 15 minutes).

Problem Description

If I set the minuteInterval to 15 and open the picker without making any manual changes to the time, the confirmed value does not respect the interval. For example:

•	Current time: 10:34
•	Configured interval: 10:00, 10:15, 10:30, 10:45, etc.
•	Picker’s position: 10:30

When I open the picker and directly confirm without switching the time, the value that gets set is “10:34” instead of “10:30”. I have to manually reselect the correct time for the picker to apply the interval properly.

Steps to Reproduce

1.	Set up a datetimepicker in datetime mode.
2.	Configure a minuteInterval (e.g., 15 minutes).
3.	Open the picker and confirm without changing the time.

Expected Behavior

I would expect that when the picker is opened and “Confirm” is pressed without modifying the time, the returned value should respect the configured interval (e.g., “10:30” instead of “10:34”).
