I’d like to request two enhancements to the DateTimePicker:

Custom Timezone (e.g., UTC): Allow the ability to set a custom timezone, overriding the system clock for consistent time handling (e.g., UTC).

Timezone-Aware "Now" Button: Enable the "Now" button to respect the selected timezone. For example, if the timezone is set to UTC and the current UTC time is 12:00:00, clicking "Now" should display 12:00:00 instead of the local time.

These features would improve flexibility for timezone-specific applications and ensure consistency in timestamp-based operations. Thank you for considering this request!
