Comment 6 for bug 263524

Why is it useful to know what timezones people are in?

If what you really want to know is whether it's okay to call a particular person, an anonymous list of local times won't help. Instead, you want to know whether the person is likely to be available (bug 264699 is an excellent idea!), or failing that you want to know what the local time is for that person, so it should be on their profile page.

If what you really want is to organize a meeting of a longitudinally-distributed team, again the list of local times won't help. What would help is a bar graph of how many team members are available at each hour.
