You could put in custom javascript code to do that. Put up the following function in the onLoad event for that page (change the value 15 to reflect the intervals that you want):
$('.icon-calendar').parent().bind('click', function () {
$('#minSelect option').each(function () {
var number = parseInt($(this)[0].text, 10);
if (number % 15 != 0) $(this).remove();
});
});
For example, if this is a Create New Object page, you could reach the onLoad event area by navigating Object definition -> Pages -> Action New -> Properties
I'm afraid there is no way of changing that today. I suggest you post an Idea on community.progress.com/.../default.aspx if want such a feature to happen.
