Quartz.net在UTC时间创建每日计划

Question

我想在每天早上8点(UTC时间)开始工作.问题是触发器不尊重我告诉它的时间.

我的代码如下:

    ITrigger trigger = TriggerBuilder.Create()
        .WithDailyTimeIntervalSchedule(
             s => s.WithIntervalInHours(24)
                 .OnEveryDay()
                 .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(8,0)))
        .Build();

   var times = TriggerUtils.ComputeFireTimes(trigger as IOperableTrigger, null, 10);

   foreach (var time in times)
       Console.WriteLine(time.UtcDateTime);

输出是:

30/09/2013 10:00:00 PM
1/10/2013 10:00:00 PM
2/10/2013 10:00:00 PM
3/10/2013 10:00:00 PM
4/10/2013 10:00:00 PM
5/10/2013 10:00:00 PM
6/10/2013 9:00:00 PM
7/10/2013 9:00:00 PM
8/10/2013 9:00:00 PM
9/10/2013 9:00:00 PM

6小时变化的原因是夏令时从本周末开始.

我怎么才能让它在UTC时间上午8点触发,就像我告诉它的那样？

编辑:这很疯狂,它甚至可以用Cron计划表达:

ITrigger trigger = TriggerBuilder.Create()
    .WithCronSchedule("0 0 8 * * ?")
    .Build();

var times = TriggerUtils.ComputeFireTimes(trigger as IOperableTrigger, null, 10);

foreach (var time in times)
    Console.WriteLine(time.UtcDateTime);

输出:

30/09/2013 10:00:00 PM
1/10/2013 10:00:00 PM
2/10/2013 10:00:00 PM
3/10/2013 10:00:00 PM
4/10/2013 10:00:00 PM
5/10/2013 9:00:00 PM
6/10/2013 9:00:00 PM
7/10/2013 9:00:00 PM
8/10/2013 9:00:00 PM
9/10/2013 9:00:00 PM

Answer 1

在下载源代码并深入研究之后,我找到了几个解决方案.

我最初找到了这样的解决方案:

var trigger4 = new DailyTimeIntervalTriggerImpl
{
    StartTimeUtc = DateTime.UtcNow,
    StartTimeOfDay = new TimeOfDay(8, 0, 0),
    RepeatIntervalUnit = IntervalUnit.Hour,
    RepeatInterval = 24,
    TimeZone = TimeZoneInfo.Utc
};

...这导致我调整我的原始代码:

ITrigger trigger2 = TriggerBuilder.Create()
    .WithDailyTimeIntervalSchedule(
        s => s.WithIntervalInHours(24)
            .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(8, 0))
            .InTimeZone(TimeZoneInfo.Utc))
    .Build();

这两个都给了我我想要的东西.我只是希望这个库有一些不错的文档.

虽然这是旧的，但我还是会在这里回答。您可以简单地执行以下操作：

ITrigger trigger = TriggerBuilder.Create() .WithCronSchedule("0 0 8 * * ?", cron => { cron.InTimeZone(TimeZoneInfo.Utc); } ) .Build();
