T.I. Going to Jail for 2 Months???

Now I am not that familiar with the court system and exactly how prison sentences work (thank god), but apparently everything is not exactly how it seems. For a while now we have been knowing that rapper T.I. has been sentenced to a year and a day in prison, but what I didn't know is that he will only be serving about two months of his sentence in Arkansas's Forrest City prison. According to the Associated Press "Harris (T.I.) will be credited for 305 days of home detention he already has served after being charged, so his stay at the Forrest City prison likely will be only two months." So basically T.I won't be gone long enough for anyone to miss him.
