Building a meeting poll across time zones

Convert each candidate meeting time for every participant before sending the poll. Include the calendar date, day of week, and named time zone—not just an abbreviation that might mean different things elsewhere.

Use Timezone Converter for the specific meeting date, since daylight-saving changes can alter offsets. Remove options that fall at unreasonable local hours and leave enough time for replies before the meeting.
