If you're using Spring you could use:

CronTrigger trigger = new CronTrigger(cron);
TriggerContext context = new TriggerContext() {

public Date lastScheduledExecutionTime() {
    return null;
}

public Date lastActualExecutionTime() {
    return null;
}

public Date lastCompletionTime() {
    return null;
}
};
return trigger.nextExecutionTime(context);
