Quartz.NET ScheduledFireTimeUtc 当超过1分钟时出现的问题。

验证代码：

    class Program
    {
        public static IScheduler scheduler = null;
        static void Main(string[] args)
        {
            scheduler = StdSchedulerFactory.GetDefaultScheduler();
            scheduler.Start();
            string GroupName = "DateRules";
            string RunCorn = "0 " + DateTime.Now.AddMinutes(1).Minute + " * * * ?";
            for (int i = 0; i < 30; i++)
            {
                string Identity = "DataRule_" + i;

                JobDataMap JobData = new JobDataMap();
                JobData["Index"] = i;
                IJobDetail job = JobBuilder.Create<MyJob>()
                   .WithIdentity(Identity, GroupName)
                   .SetJobData(JobData)
                   .Build();

                ITrigger trigger = TriggerBuilder.Create()
                    .WithIdentity(Identity, Identity)
                    .WithCronSchedule(RunCorn)
                    .Build();

                scheduler.ScheduleJob(job, trigger);
            }
            Console.ReadLine();
        }

    public class MyJob : IJob
    {
        public void Execute(IJobExecutionContext context)
        {
            var FireTimeAfter = context.Trigger.GetFireTimeAfter(context.ScheduledFireTimeUtc.Value.ToLocalTime());
　　　　　　　　
            string Index = context.JobDetail.JobDataMap["Index"].ToString();
            Thread.Sleep(30000);
            Console.WriteLine( FireTimeAfter.Value.ToLocalTime() + "	" + context.ScheduledFireTimeUtc.Value.ToLocalTime() + "	" + Index);
        }
    }

quartz本身包含一个线程池，让线程池中所有线程都Sleep30秒后输出ScheduledFireTimeUtc为示例：2019-09-17 09:00:00 ，当Sleep超过1分钟再启动的Job的ScheduledFireTimeUtc变为了:2019-09-17 09:01:00 

这时使用使用GetFireTimeAfter重新取得应执行时间。
