I am in the pacific time zone, looking at driving times in Ontario, Canada.

I have heard that traffic can be bad, so I want to figure out expected driving time to the Toronto airport.

But when I dial up times in Google Maps (see below), it is unclear to me what time zone the times refer to. Are the times my browser/PC Clock time zone (pacific), or are they the local time zone of the start or ending locations dialed up in maps?

Is there some google documentation I can refer to? (I didnt find any)
