Timestamp was outputting H:I:S, changed to H:M:S

When converting, the script would show the time incorrectly.

For example:

"2013-02-12 17:11:14 -0000"

was being converted to

"17:05:14"

because I is 12 hour clock Hours.
Merge pull request #1 from cluebattery/master

The times are incorrectly being shown as Hour:hour:Second - this is fixed in this commit.
