epoch time



I understand that the departure/arrival times are epoch time. It might be a naive question, but I’m wondering if the epoch time already has taken into account the time zone differences for European and US airports?

For example, AAL100 is scheduled to take off at 1357946100 (parsed as 07:09:00 of that day) at KJFK, while AAL109’s departure time is 1357898100 (parsed as 07:18:00 of that day) at EGLL. So are they really 9 minutes apart in departure time?





If you need to convert epoch times to local times at that airport, you can use the “AirportInfo” function to retrieve the timezone identifier once, and then use tzdata/zoneinfo APIs to transform each epoch into local time for that timezone identifier.


Thank you both.
