Perth, Australia is UTC+8 · Denver, the United States is UTC−7 — on standard time

Perth stays put all year while Denver moves, so the gap changes twice a year from Denver's side alone. A recurring meeting set in Perth's calendar will drift by an hour without anyone touching it.

When they can both be at their desks

Nine-to-five in Perth and nine-to-five in Denver do not overlap at all. With 14 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
