Obtains an instance of LocalDateTime from an Instant and zone ID.

Usage

From source file:Main.java

public static void main(String[] args) {
    LocalDateTime a = LocalDateTime.ofInstant(Instant.now(), ZoneOffset.UTC);

    System.out.println(a);
}

From source file:Main.java

public static void main(String[] args) {
    Date date = new Date();
    LocalDateTime localDateTime = LocalDateTime.ofInstant(date.toInstant(), ZoneId.systemDefault());

    System.out.println(localDateTime);
}

From source file:Main.java

public static void main(String[] args) {
    Instant instant = Instant.now();
    LocalDateTime dateTimeFromInstant = LocalDateTime.ofInstant(instant, ZoneId.of("America/Los_Angeles"));
    Instant instantFromDateTime = LocalDateTime.now().toInstant(ZoneOffset.ofHours(-2));

    System.out.println(dateTimeFromInstant);

    System.out.println(instantFromDateTime);
}

From source file:Main.java

public static void main(String[] args) {
    // Date to Instant
    Instant timestamp = new Date().toInstant();

    // convert Instant to LocalDateTime or other similar classes
    LocalDateTime date = LocalDateTime.ofInstant(timestamp, ZoneId.of(ZoneId.SHORT_IDS.get("PST")));
    System.out.println("Date = " + date);

}

From source file:Main.java

public static void main(String[] args) {
    // Instant is useful for generating a time stamp to represent machine time.
    Instant timestamp = Instant.now();
    // Convert "machine time" to human units
    LocalDateTime humanTime = LocalDateTime.ofInstant(timestamp, ZoneId.systemDefault());

    System.out.println(humanTime);
}

From source file:Main.java

public static LocalDateTime localDateFromTimestamp(Timestamp timestamp) {
    return LocalDateTime.ofInstant(timestamp.toInstant(), ZoneOffset.ofHours(0));
}

From source file:Main.java

public static LocalDate fromDate(Date date) {
    Instant instant = Instant.ofEpochMilli(date.getTime());
    return LocalDateTime.ofInstant(instant, ZoneId.systemDefault()).toLocalDate();
}

From source file:Main.java

public static LocalDateTime getDateTimeFromTimestamp(long timestamp) {
    if (timestamp == 0)
        return null;
    return LocalDateTime.ofInstant(Instant.ofEpochSecond(timestamp), TimeZone.getDefault().toZoneId());
}

From source file:Main.java

public static LocalDate getLocalDateFromDate(Date date) {
    return LocalDateTime.ofInstant(new Date(date.getTime()).toInstant(), ZoneId.systemDefault()).toLocalDate();
}
