Excel 2013 :: Extract Date And Time Info From A Text Cell That Contains Text And Date And Time

I am using Excel 2013. Anyway, the first issue is that I need to pull a date and a time period from text. So, for example, if I see something like Sunday Prime Time 7/6/14 8:37PM, I would want to pull ONLY the "7/6/14 8:37PM" out of it. Each text box could potentially be different, so it might not always be in the same format as "Sunday Prime Time 7/6/14 8:37PM" it might only show just the date and/or the time without all the extra text i.e. 7/6/14 8:37PM. Some of the cells will have text, others might only have just the time or even just the date and the time. The only thing that I am worrying about in each cell is extracting just the date and time. If this is too much to ask of excel, I would be ok with extracting ONLY the time - 8:37PM and not the date, but I would much rather be able to get both the time and date.

THEN, onto part two of my question. After I would pull the dates and times, I need to compare them with each other. So, when I have the same date with two separate times on that date, I need to write a formula to show if those times on that date are less than 30 minutes apart. So, if I have 6 times on 7/6/14, I need to know if any of them are less than 30 minutes apart.

I would need to have the formula say something like "Problem" if the times on 7/6/14 would be 5:30PM, 5:48PM, 7:00PM, 8:00PM, 8:15PM, and 9:00Pm for example. I would like to see the word "Problem" since 5:30PM and 5:48Pm is only 18 minutes apart, and "Problem" after 8:15PM since that is only 15 minutes past the 8:00PM which is obviously under 30 minutes. The times that are more than 30 minutes apart such as 7:00PM and 9:00PM for example are more than 30 minutes apart from any of the other times that were extracted.
