public class DefaultTimeTickCalculator
extends AbstractTimeTickCalculator

A default implementation of a tick calculator for time-based axes. Note that if you want to use a specific time zone for your display, you have two options: either call setTimeZone() if you want to use the default date formats, or use setDateFormat() if you want to specify the date format yourself and set the TimeZone on the DateFormat object.
