So I wonder why people haven't been asking the core team to change the confirm time on the next hard fork? This is a perfect time to do it considering we're very likely going to be doing a hard fork any way to increase the block size from 1 mb.
It takes about 1 hour to make sure the confirmation is solid due to orphan blocks or some kind of attacks. 6 confirmation of 10 minute block takes 1 hour. If you reduce the block time to 1 min, then it will take 60 confirmation to avoid double spend.
