i actually don't time it because it's something i do through out my day even at work when i'm talking to God to stay positive , you have to always make time for God. although sometimes when i'm trying to read God's word in the break room before starting work someone will see you reading the Bible and start a conversation , while you are trying to stay focused .
one of my coworkers we would walk the floor we would be working on and pray the length of the floor . our day would always go great
just think about all the non important things we freely give our time too,
