Date and time conventions

Overview of time and date conventions

GoToMeeting, GoToWebinar, GoToAssist, and GoToTraining

In all POST calls, use the UTC date format, 2015-12-11T09:00:00Z (i.e., include the trailing Z), to ensure correct creation of dates. In all cases, you should also declare the organizer's local time zone. This ensures the event displays in the organizer's time zone in the Admin Center for GoToMeeting, GoToTraining, and GoToWebinar. These practices also result in consistent and correct treatment of dates in other APIs. If you omit either or both values, inconsistent behavior for event dates and times can result.


The GoToAdmin reports use a millisecond time format. For example, at this writing, on May 12, 2020 at 11:00:54 local time, the millisecond value is 1589306454933.

Time zones

Time zone reference (based on ICANN tz data) - use the tz database name for time zones in API calls.
