Actually, when I heard this, it totally resonated with me. I don't know if it is an "actual" condition or not, but I definitely have it. I have always had problems keeping track of events in the past, unless I can actually assign a date (like graduating from nursing school, or 9-11). Likewise, I have difficulty with future concepts, such as a "five year plan," et al.
When I heard the TV character use this term, I had to write it down, if for no other reason than to have a way to explain myself!
