How-To: Trigger That Executes Every Day
If you want a trigger that always fires at a certain time of day, use CronTrigger or CalendarIntervalTrigger because they can preserve the fire time’s time of day across daylight savings time changes.
Create a CronTrigger. that executes every day at 3:00PM:
trigger = newTrigger() .withIdentity("trigger3", "group1") .startNow() .withSchedule(dailyAtHourAndMinute(15, 0)) // fire every day at 15:00 .build();
Create a SimpleTrigger that executes 3:00PM tomorrow, and then every 24 hours (which may not always be at 3:00 PM - because adding 24 hours on days where daylight savings time shifts may result in 2:00 PM or 4:00 PM depending upon whether the 3:00 PM time was started during DST or standard time):
trigger = newTrigger() .withIdentity("trigger3", "group1") .startAt(tomorrowAt(15, 0, 0) // first fire time 15:00:00 tomorrow .withSchedule(simpleSchedule() .withIntervalInHours(24) // interval is actually set at 24 hours' worth of milliseconds .repeatForever()) .build();
trigger = newTrigger() .withIdentity("trigger3", "group1") .startAt(tomorrowAt(15, 0, 0) // 15:00:00 tomorrow .withSchedule(calendarIntervalSchedule() .withIntervalInDays(1)) // interval is set in calendar days .build();
