Quick! Which of these two is older?
Errr… Oh! The one with the apostrophe!
Took you a second, didn’t it?
I took an impromptu poll on IRC to confirm this:
<ii> riking_: it doesnt say if its feb 2013 or 13th of feb etc <ii> the '13 would suggest 2013 tho (after getting it wrong) <culex> I thought Feb didn'th ave the apostrophe <Malqua> no <Malqua> it was definitely jan ??, 13
I think that the date formats, even for English, should be changed to DD Mmm (so 13 Jan) and Mmm 'YY (the current, so Feb '13). This way, they are visually different.
