Simple Vs Cron Triggers, Quartz Crontrigger

i previously left a question regarding firing a trigger on a given time...
I gave it further study...
Using this snippet:

JobDetail jd2 = new JobDetail( "hellojob", "group", HelloJob.class );

//will run every 5 minutes starting from minute it was launched
String cron = "0 " + new Date().getMinutes() +"/5 * * * ?";

CronTrigger cronTrigger2=new CronTrigger( "cron2", sched.DEFAULT_GROUP,cron );

sched.scheduleJob( jd2, cronTrigger2 );

sched.start();

The snippet will have to run will run every 5 minutes starting from minute it was launched but will run again starting from the minute it was first launched. For example I launded it at 5:54 PM, it will run again at 5:59 PM and then next at 6:54 PM then at 6:59 PM. Not a very good idea.

If you will have to use a scheduler that will have to run every X minute, consider using simple triggers. The default start time is from the time it was launched but he start time and end time can also be defined.
