Incorrect executionTime

[sunshine7690]

public static void main(String[] args) {
CronDefinition definition = CronDefinitionBuilder.instanceDefinitionFor(CronType.QUARTZ);
CronParser parser = new CronParser(definition);
Cron cron = parser.parse("*/8 * * * * ?");
ExecutionTime executionTime = ExecutionTime.forCron(cron);
ZonedDateTime now = ZonedDateTime.of(2024, 9, 12, 10, 46, 57, 0, ZoneOffset.UTC);
System.out.println("now "+now.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
now = executionTime.nextExecution(now).get();
System.out.println(" nextExecution "+ now.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
}

Run the code. result is:
now 2024-09-12 10:46:57
nextExecution 2024-09-12 10:47:00

During cross-minute, the next execution time is incorrect.
