Method compareTo

src/main/java/com/amazon/ion/Timestamp.java:2767–2783

Performs a comparison of the two points in time represented by two Timestamps. If the point in time represented by this Timestamp precedes that of t, then -1 is returned. If t precedes this Timestamp then 1 is returned. If the Timestamps represent the same point in ti
