Ottawa keeps two clocks.
Ottawa runs on North America's Central/Eastern rhythm — synchronized with Toronto's clock, the city's public life and workday start early and wrap by early evening, giving long, bright summer evenings that most of the world calls its lunch hour, so global teams should remember Ottawa's day is basically over when the West Coast is just hitting peak productivity.
