Episode is set between 4pm and 5 pm, however shortly before time is announced as 4:28:07, you can see Carter's phone showing time as 5:49pm.
Near the end of the episode, at around 41 minutes Eric Carter said "stay put, or I will shoot you in the other knee". His gun was out of bullets when he said this. The slide of the gun was pulled back, which indicates that he fired his last bullet. I think the bad guy should have noticed that too.
