我每天早上8点准时开始工作。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);
输出结果为:
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。
我如何才能让它在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计划来实现:
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
答案 0 :(得分:15)
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
};
...这让我调整了原始代码:
ITrigger trigger2 = TriggerBuilder.Create()
.WithDailyTimeIntervalSchedule(
s => s.WithIntervalInHours(24)
.StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(8, 0))
.InTimeZone(TimeZoneInfo.Utc))
.Build();
这些都给了我我追求的东西。我只是希望这个库有一些不错的文档。

虽然这已经过时了,但无论如何我都会在这里回答。您只需执行以下操作:
ITrigger trigger = TriggerBuilder.Create()
.WithCronSchedule("0 0 8 * * ?", cron => { cron.InTimeZone(TimeZoneInfo.Utc); } )
.Build();
