This is no joke... We have more than enough people that have been deployed to Afghanistan that should be able to answer this question.
Most Afghan's don't own a watch or have power in their homes. So if your talking to a Afghan and you ask him what time did XYZ happan. How can he tell you?
Most Afghans can't read or write their own langauge. Most can't speak it properly; like us American's. Me included in this!!

Most Afghans don't know the days of the week, months within a year.
So if you ask a Afghan when did this happen? Better, when were you born? How can he answer you?
BTW - I really hate people putting January as that enter date for DOB, ETC.
BLUF - How does a Afghan tell time?
Why is this important with VSO? Why is it important period for that matter?
