+ * <p><b>Absolute Time:</b> This refers to real world wall clock time, and it typically
+ * derived from a system clock. It is subject to clock drift and inaccuracy, and can jump
+ * if the system clock is adjusted.
+ * 
+ * <p><b>Relative Time:</b> This time advances at the same speed as the <i>absolute time</i>,
+ * but the timestamps can only be referred to relative to each other. The timestamps have
+ * no absolute meaning and cannot be compared across JVM processes. The source for the
+ * timestamps is not affected by adjustments to the system clock, so it never jumps.
