Normalize milliseconds in picked dateTime to 0

Summary

This change sets the milliseconds of a picked dateTime to 0. This ensures consistency and avoids issues when comparing Date objects modified by the datetime picker.

Motivation

When using the datetime picker, the inclusion of milliseconds can lead to unexpected behavior during date comparisons. For example when pick 2025-01-01T16:00+0100 in the DateTimePicker and do this comparison.

new Date('2025-01-01T16:00+0100') >= <DatePickedWithDateTimePicker>

This comparison will always return false due to the additional milliseconds present in the picked dateTime.

Proposed Solution

By normalizing milliseconds to 0, the behavior aligns with the existing practice of setting seconds to 0. This ensures:

• More intuitive and predictable behavior.
• Easier comparisons between Date objects.

Expected Behavior

• The milliseconds of all picked dateTime values will now default to 0.
• Comparisons like the example above will behave as expected.

Additional Notes

This change is consistent with the datetime picker’s behavior of setting seconds to 0. It enhances the overall usability and developer experience.
