I'd really, really like to know what times each moderator and candidate feels are their most SF-productive expressed in UTC.

The reason for the question is that SF seems to have users - and consequently problems needing moderator attention - from all over the world, now, and I sometimes get the feeling that the existing moderators are clustered in terms of what times they tend to be on. At some times of day, I see flags getting attended to with super efficiency, but at other times, I get the vague impression that they languish somewhat.

It seems to me that if we ended up with, say, most moderators being in the US, and some in the UK, and they all did most of their moderation in working hours (and I'm not saying that's the case, only using a hypothetical example), we'd have good moderator cover from about 0900UTC to 2400UTC, but not so much in the remaining time. In such circumstances, I'd look more favourably on a candidate from, say, Vietnam or Australia, who spent most of her time on SF during her working day, than on an otherwise-stellar working-hours candidate from, say, Germany, or an evening-hours candidate from the UK.

So, existing moderators and candidates: if you don't think this is a completely stupid question, would you mind saying in UTC what your "core SF hours" tend to be?

Edit: they say a picture is worth a thousand words, so I've tried to express people's estimates of their core hours on weekdays into the diagram below. Current moderators are in green, candidates in red; solid boxes are peoples' "solid" hours, whilst boxes in outline are maybe/sometimes hours. I hope it's OK to do this, and that it will be helpful.
