I'm not thrilled about the calendar changes in the first place. We've had OoC holidays line up with IC ones ever since way-back-then.
I can accept that Yamatai's planet rotates around its sun differently, spins faster and so forth to make different local time, but I would have still kept universal time the same.
So, from my point of view, the cage was already rattled and I'm still not sure how much I like this, neither do I know how I'll cope with this.
This proposal rattles the cage further. I was for slowing time down before, and I've been villified for it back when I was co-admin (with the OoC years packed into 1 IC one waved to me since then like some brand of shame). You prefered the IC year to match the OoC year too. But now, you want it to be slower? Can you explain why you'd favor that - because, so far, in all honesty my attitude to this borders the "make up your damn mind" here. >_<
So, basically, none of the above. An IC year should still be 12 months.
