RFR:8143413:add toEpochSecond methods for efficient access

[Stephen Colebourne]

This is based on user difficulties picked up via Stack Overflow. These
methods aim to provide a simpler and faster approach, particularly for
cases converting to/from java.util.Date.

For the time cases, the convention of 1970-01-01 is natural and
commonly used in many codebases.
