In the current weekly comic thread, somebody cited a post Jeph made three years ago about the ages of the different characters. I was surprised, because despite their being eight years of development at that point, all of the characters were still the same age as the start of the comic. E.g. Marten is still 24 or 25 (never been said), Dora is still 26, etc. This means in the entire are of the comic to that point that presumably only a year of in-comic time (or less) had gone past. In a sense this isn't surprising. AFAIK there was only one time that Jeph skipped time ahead - during Marten and Dora's relationship. Which was probably a good choice, because given the pacing of the comic if it only skips forward a day or two at a time, they wouldn't have had anything resembling a long-term relationship. It also puts the development of characters into perspective - people are going through incredibly huge changes in only a year's time!
The question remains though - what is actually happening regarding time in QC. I note a couple of things:
1. No one (IIRC) has had a birthday during the strip. This would seem to say that people are actually pepetually at their current age, Simpsons like. However, characters (most recently Tai) have graduated from college in strip, which would seem to suggest people are still achieving milestones.
2. Early on in the thread, Marten is explicitly shown with a yearbook from HS with 1998 on it. This would seem to imply that QC remains about a decade in the past compared to us. However, people have Iphones and the like, which seems to suggest it's somehow become contemporary. Unless having iphones and the like is just part of the weird futuretech that the QCverse has access to.
Anyway, I was wondering if anyone else had more ideas regarding this.
