In my own anecdotal experience, this appears quite reasonable; oftentimes, especially in childhood, stretches of time as short as 1 week into the future would "feel" (i.e. encompass the same emotions/sensations) as knowing how far away my relatives in Canada were from me. The perception of time seriously befuddled my brain for years -- no matter that it still does to this day!
If you happen to recall the outlets you read this at, I would be interested in learning more. Hopefully the article would have links to papers as well... perhaps including fMRI scans? Truly fascinating stuff.
