Schedule invalid next action times when start time is in the future

Hi team,

If we create two similar schedules but set one to start only one hour from now, the getNextActionTimes() returns invalid values.

Instant now = Instant.now();

List<ScheduleCalendarSpec> calendarSpec = List.of(
    ScheduleCalendarSpec.newBuilder()
        .setSeconds(List.of(new ScheduleRange(now.atOffset(ZoneOffset.UTC).getSecond())))
        .setMinutes(List.of(new ScheduleRange(now.atOffset(ZoneOffset.UTC).getMinute())))
        .setHour(List.of(new ScheduleRange(0, 23)))
        .build());

System.out.println("Now: " + now);
for (int i = 0; i <= 1; i++) {
    scheduleClient.createSchedule("scheduleId" + i,
        Schedule.newBuilder()
            .setAction(action).setSpec(ScheduleSpec.newBuilder()
                .setStartAt(now.plus(i, ChronoUnit.HOURS))
                .setCalendars(calendarSpec).build()).build(),
        ScheduleOptions.newBuilder().build());
    System.out.println("Schedule " + i);

    scheduleClient.getHandle("scheduleId" + i).describe().getInfo()
        .getNextActionTimes().forEach(System.out::println);
}

Output of this code:

Schedule 0
2024-05-27T19:22:10Z
2024-05-27T20:22:10Z
2024-05-27T21:22:10Z
2024-05-27T22:22:10Z
2024-05-27T23:22:10Z
(...)
Schedule 1
2024-05-27T19:22:10Z
2024-05-27T19:22:10Z
2024-05-27T19:22:10Z
2024-05-27T19:22:10Z
2024-05-27T19:22:10Z
(...)

I would expect the hours for Schedule 1 to start at 2024-05-27T20:22:10Z and increment by one hour just like Schedule 0.
Why does this happen? Is this a expected behaviour?

Thank you.
