Cron expression with start and end time - cron

Question

I am trying to write an cron expression with a specific start time and end time everyday. i.e.
every minute from 10:15 to 17:35 everyday
One possible solution for this is writing 3 different cron expressions like this:
0 15-59 10 * * *
0 * 11-17 * * *
0 0-35 17 * * *
Is there any possible way to write this in one single cron expression ?

Answer 1

There is no other way to achieve it using single crone expression but to specify multiple crone expressions for specific startDate and endDate.
There is a slight modification in second crone expression though (highlighted one)
0 15-59 10 * * * (Every minute between 10:15 AM and 10:59 AM)
0 * 11-16 * * * (Every minute, between 11:00 AM and 04:59 PM)
0 0-35 17 * * * (Every minute between 05:00 PM and 05:35 PM)

Answer 2

Quartz Scheduler c#
run job between to hours
use corn mask:
ITrigger trigger_1 = TriggerBuilder.Create()
.ForJob("YOUR_JOB")
.WithIdentity("trigger_1")
.StartAt(startTime)
.WithCronSchedule("0 0/1 8-13 ? * SUN,MON,TUE,WED,SAT *")
.Build();
use Quartz Schedule:
trigger_1 = TriggerBuilder
.Create()
.ForJob("YOUR_JOB")
.WithIdentity("trigger_1")
.StartAt(startTime)
.WithDailyTimeIntervalSchedule(c => c
.OnEveryDay()
.WithIntervalInMinutes(1).WithRepeatCount(1)
.StartingDailyAt(new TimeOfDay(08, 30))
.EndingDailyAt(new TimeOfDay(12, 30))
)
.Build();
