Garmin Connect Web Jet Lag Advisor Times are Confusing

I noticed when adding a trip in the Jet Lag advisor there is no indication of the time zone. I assume that the time for departure and arrival is the local time of the city suggested. However it might make more sense to be explicit about this on the website - otherwise people could easily put their arrival time in their _local_ time (which would be easy to do as at the time of entering the data you'd see the arrival time as local time in your calendar or whatever).

Does anyone know how to suggest changes like this?
