Case in point:
21-Oct-2006 B763/W Sheremetyevo (UUEE) Hartsfield Jackson Atlanta Int’l (KATL) 18:53 GMT 16:52 EDT 1:59
There’s no way a B767 can make it from Sheremetyevo to Atlanta in 2 hours. What it looks like, the TZ offset for Moscow was applied to the local time in Moscow backwards, and the correct departure time must be 10:53 GMT. Same thing seems to happen for every flight originating in Europe.
Please excuse me if this bug has been discussed already.
