You might be thinking of this paper:

Michael W. Davis and Tadeusz Januszkiewicz, Right-angled Artin groups are commensurable with right-angled Coxeter groups, J. Pure Applied Algebra, 153, No. 3 (2000), 229-235.

does every right-angled coxeter group have a right-angled artin group as a subgroup of finite index?
I have my datetime stored as string:

"20120515 061115"


would be 

"May 15, 2012 at 6 hour 11 minutes 15 second"


How do I convert this to datetime?  Maybe using the "CDate" function?
