analyzing time

Hello All,

I have a table with a column of type date, with dates and time combined (like '1/6/2013 3:52:69PM'), that spans many months.  How would I pull out records that are the first and last entries per day?

Also, if I wanted to find time clusters per day (or per week) -- like if an entry is made every day around 11am -- is there a way to get at that temporal statistical cluster?

Python 2.7, Windows 7.

Any guidance would be greatly appreciated!  Time seems tricky...

Thanks,

N
