Hi Roger,

I'll be home for a bit if you want to call

Otherwise let's talk tomorrow

This is a plot of the NY var event (cum of 5 events) for different selections of timezones

I use the N largest zones, by pop, where N is the number of the zones.

so zone set 24 uses the 24 most populous timezones.

C30 and C20 are the complements of the 30 and 20 zone sets; these are sets with least populations.

I also looked at examination periods broader than the 10 minutes centered on midnight.

Most of the sets exclude 2 zones: Nepal and Chatham Islands. These zones are shifted by 15 minutes which makes the periods overlap when I look beyond -5 +5 minutes. Shouldn't be a big deal to exclude them.

It's interesting to see that the complement zones are indeed weak. More needs to be done for this analysis...
