No.

The reflog records how _you_ modified your various branches locally.  
This has no direct relationship with the dates the commits in those 
branches were created.  It records what was your own view of the 
repository in time.  So if you performed an import of a SVN repository 
last week, then it is normal that you don't have any view into that 
particular repository's state before last week.

Have a look at the documentation for the --pretty=format option in the 
git-log man page.  For example:

	git log --pretty=format:"%H %ai"

might be just what you're looking for.
