Replacements

java.util.Date     => java.time.Instant
java.sql.Timestamp => java.time.Instant
java.sql.Date      => java.time.LocalDate
java.sql.Time      => java.time.LocalTime

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).All three java.time.Local… classes are all lacking any concept of time zone or offset-from-UTC.
