Your study calendar always displays in your own local timezone, and every participant sees session times automatically converted to theirs. You never need to convert times for participants.
What timezone is my study set to?
Session times in your calendar are based on where you are, just like Google Calendar. If you set up sessions from New York, a colleague viewing the same study from London sees the calendar shifted to London time.
Note: if you're using a VPN, it can affect the timezone your calendar displays in.
What timezone do participants see?
Participants always see session times in their own local timezone. The conversion is automatic.
For example: your timezone is Sydney (AEDT) and you confirm a session for 10am. A participant in Brisbane (AEST) sees it as 9am, and a participant in Perth sees 7am. They're all the same session.
Setting up sessions for a global team
If facilitators in different timezones are running sessions on the same study, the simplest approach is:
Set up the rest of your draft study.
Ask each facilitator to add their own session times to the calendar, so the times are entered in their local timezone.
Make sure each person saves the draft before leaving.
If one person is adding sessions on behalf of overseas colleagues, use a time converter and remember the calendar still displays in your local timezone.
Best practice: create and manage your own sessions wherever possible.
Why does the chat show a different time?
When you message a participant in another timezone, session times quoted in the message thread can look different from what you booked. That's because you're seeing a snapshot of what the participant sees, in their timezone.
Always rely on your calendar or participant list for the true session time in your own timezone.
