You can enable time zone support during step 2 of poll creation. Click ‘use time zones’ just below the calendar to enable it.
When you enable time zone support, Doodle automatically sets the correct time zone for each of your participants. Your time options will be displayed corresponding to where they are located (according to their IP address or Doodle account setting). Otherwise, the poll is set up with certain times and shows this time for everyone. It does not matter where someone opens the poll. It will always show the same times.
Keep in mind that this setting can’t be turned on or off after you create the poll. If you’ve already created the poll, you’ll have to duplicate it and then enable this setting in step 2, or create a new poll.
