My experience provides a few counter examples, and I think in the world of making little items out of an SOC and some code, my examples are highly representative, so I wonder if you have a good source to back your supposition. I had a project at one large company, where a daily conference call was scheduled at 8AM Pacific Time, my local zone, so that the guy in France could attend at a reasonable hour. There were attendees in various other "Western" locations. The time zones ranged from -8 to +1. Nowadays I see this happening with virtual companies, who rent offices all over the place and barely own anything. When I have dealt with such, no one has been expected to be operating more than 8-10 hours at a time. Expectations of email response are patiently kept in accord with the time zones of the recipients.
