Random time and date

Question

I want to get a date that generates the time from now to 2685 days back and a random time. The format I accept must be "uuuu-MM-dd'T'HH: mm: ssZ". Currently my program is generating a random date but I am not able to create a random time because Duration conflicts with Period

public static String generateRandomDateAndTimeInString() {
    LocalDate date = LocalDate.now()
            .minus(Period.ofDays((new Random().nextInt(2685))));
    return formatDate(date);
}

public static String formatDate(LocalDate date) {
    DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuu-MM-dd'T'HH:mm:ssZ");
    return date.atStartOfDay().atOffset(ZoneOffset.UTC).format(dtf);
}

Something like this may be?

public static String generateRandomDateAndTimeInString() {
    ThreadLocalRandom random = ThreadLocalRandom.current();
    LocalDate date = LocalDate.now()
            .minus(Period.ofDays((random.nextInt(2685))));


    LocalTime time = LocalTime.of(random.nextInt(0, 23), random.nextInt(0, 59), random.nextInt(0, 59));

    return formatDate(LocalDateTime.of(date, time));
}

public static String formatDate(LocalDateTime date) {
    DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuu-MM-dd'T'HH:mm:ssZ");
    return date.atOffset(ZoneOffset.UTC).format(dtf);
}
