Fixed post/newPost, Added Post Printing

Removing the rss url at the start cause checking to be impossible.
because there is nothing to compare against. Re-added post at start, if
a new post is found, it now prints it.
Lowered Sleep Time, Fixed Time and Date Formatting

30 second sleep was resulting in posts not being shown due to deletion.
Can change later based on needs. Fixed the formatting for the date and
time.
