NZST to MST: convert New Zealand Time to Mountain Time

Scheduling a call between NZST and MST
Standard business hours (9:00 AM to 5:00 PM) do not overlap in January: daytime in New Zealand Time falls outside the working day in Mountain Time, so one side needs an early morning or late evening.
In July standard business hours do not overlap at all.
