Best time picker for Vaadin 8

is there any the best time picker layout for Vaadin 8? and how to implement it?

for input to database, im using postgreSQL with timestamp format, so i can save time only. thanks

or is there no time picker in vaadin 8? so im using drop down menu or 2 fields (for hour and minute) to input it manually?

There are couple of add-ons in the Directory, but no official one in the framework in Vaadin 8. This feature was added in Vaadin14 and 23.
