Maybe i am just not searching properly, but does anyone know of a way to have the time input only increment using the spinner based on a preset interval. So if it is 10 minu
Sure, just use the step attribute, where the step specifies the number of seconds to increment (60 sec x 10 mins = 600 seconds):
<input type="time" value="08:30:00" step="600">
