Display author’s name on post…

I cannot seem to find an option to add the authors name on the post…

right now it just says

“Posted 1 day, 21 hours ago at 2:42 pm.”

thats it… i wanted to just display the date and posted by (author)…

I have gone in to my admin profile but there is no option in there… is there a code that i can insert in to the index.php or single-post.php that i can use? if so where do i put it in? haha

thank you for your help out there… i know someone knows what im talking about!

haha

Regards
