Does anyone know if in GWT we have a good TimePicker ? In fact I want a widget in order to select hour and minute for GWT.
Thanks
I know this question was asked a while ago, but I came across it during my search for a GWT time picker and I decided to write my own.

It supports many different input formats (4p => 4:00pm, 745 => 7:45am, etc) and has a drop-down menu with times at fixed intervals.
On iOS, it automatically uses an HTML5 input type="time"
