Sure it does.

If clock drift adds some measure of uncertainty to logs, such that 
you can't be sure of the precise boundary where a resource is 
allocated to one user, then that can potentially be easily exploited 
by a user. E.g.:

Step a) send nefarious email / browse whatever
Step b) disconnect/reconnect immediately thereafter

It wouldn't hide any continued patterns of abuse, but it sure seems 
like it could provide plausible deniability for specific instances..
