Adding or subtracting time to/from Instant

For adding time, Instant has a suite of methods. For example, adding 2 hours to the current timestamp can be accomplished as follows:

Instant twoHourLater = Instant.now().plus(2, ChronoUnit.HOURS);

In terms of subtracting time, for example, 10 minutes, use the following code snippet:

Instant tenMinutesEarlier = Instant.now()  .minus(10, ChronoUnit.MINUTES);

Beside the plus() method, Instant also contains plusNanos(), plusMillis(), and plusSeconds(). Moreover, beside the minus() method, Instant also contains minusNanos(), minusMillis(), and minusSeconds().
