[SOLVED] How do I make my while loop fire once a minute?

How do I make my while loop fire once a minute?

I have this while loop:

while (now() > timeToday(checkTime).time && now() < timeToday(arrivalTime).time){

I would like for this loop to run only when the real time clock's seconds hits 00 Basically allowing the loop to run once per minute. I am doing this because the IDE I am writing in only allows a 15 second pause maximum. Unfortunately sleep() is not an option at all in the SmartThings IDE

I was thinking something like this

while (now() > timeToday(checkTime).time && 
       now() < timeToday(arrivalTime).time && 
       Date.parse('ss', now() = 00).time){

But I'm fumbling with it.

If there is a better way to do this than the conditional please let me know.

Solution

SmartThings finally gave an answer back and said to use their runIn(60, myHandler) logic.

Thanks for everyones input.
