Converts this date-time to the number of seconds from the epoch
of 1970-01-01T00:00:00Z.
!(p)
This combines this local date-time and the specified offset to calculate the
epoch-second value, which is the number of elapsed seconds from 1970-01-01T00:00:00Z.
Instants on the time-line after the epoch are positive, earlier are negative.
!(p)
This implementation calculates from the epoch-day of the date and the
second-of-day of the time.
@param offset the offset to use for the conversion, not null
@return the number of seconds from the epoch of 1970-01-01T00:00:00Z
