public CronTrigger(String expression)
CronTrigger from the pattern provided in the default time zone.expression - a space-separated list of time fields, following cron
expression conventionspublic CronTrigger(String expression, TimeZone timeZone)
CronTrigger from the pattern provided in the given time zone.expression - a space-separated list of time fields, following cron

public Date nextExecutionTime(TriggerContext triggerContext)
Next execution times are calculated based on the completion time of the previous execution; therefore, overlapping executions won't occur.
nextExecutionTime in interface TriggertriggerContext - context object encapsulating last execution times
and last completion timenull if the trigger won't fire anymore
