Unfortunately, no. Those logs only provide page counts but without the associated timestamps ("when" those pages have been accessed). If such logs exist, they would perfectly do.. 
 

By comparison, the logs in that dataset looks like this:

The first token is just a counter,  the second one is a Unix timestamp then there is the Wikipedia URL in the request, and a flag indicating if the request issued a database update or not (none of those three did).

best,
