[threeten-dev] [threeten-develop] JSR 310 Final Release Materials and Review

[Douglas Surber]

The JavaDoc for Instant.MAX says

>The maximum supported Instant, 
>'1000000000-12-31T23:59:59.999999999Z'.

and for Instant.MIN says

>The minimum supported Instant, '-1000000000-01-01T00:00Z'.

This is +/- 1 * 10^9 years which conflicts with the Instant class 
description which says:

>The measurable time-line is restricted to the number of seconds that 
>can be held in a long. This is greater than the current estimated 
>age of the universe.

Long.MAX_VALUE number of seconds is more than +/- 292 * 10^9 years 
and the universe is 13.7 * 10^9 years old.

Given the class description it seems incorrect that

   Instant.MAX.compareTo(Instant.ofEpochSeconds(Long.MAX_VALUE))

returns -1.

As an aside, why 'MAX' rather than 'MAX_VALUE' as is used elsewhere?
