Provide access to SimpleTriggerFactoryBean property startTime [SPR-10940]

[spring-projects-issues]

Gerrit Hübbers opened SPR-10940 and commented

Currently, org.springframework.scheduling.quartz.SimpleTriggerFactoryBean doesn't support access to the startTime property. (see
https://github.com/spring-projects/spring-framework/blob/master/spring-context-support/src/main/java/org/springframework/scheduling/quartz/SimpleTriggerFactoryBean.java).

startTime is a useful property, as it allows specifying a precise instance in time when the SimpleTrigger shall fire for the first time.

As a workaround to emulate this property, a user can awkwardly calculate an offset from the current system time and then set the startDelay property. This workaround is also causing unneccessary scheduling imprecision.

Therefore, it is beneficial to provide direct access to the startTime property.

I've added a corresponding setStartTime method to SimpleTriggerFactoryBean as well as CronTriggerFactoryBean, analogous to the inherited setStartTime method on SimpleTriggerBean and CronTriggerBean. To be released in 4.0.1 and 3.2.7.
