Riddle me this?? Daylight savings time

Well good guess haha it was the in laws! They got delivered for the first 1:40. Apparently that was the correct time anyways. Still never got an answer as to why. I had a look at arrival and departure times for YVR and LAX that morning and couldn’t make any sense of it, it seems like neither airports have many flights arriving/departing between 12am-6am anyways so it likely didn’t confuse many people. Still in the future they should denote which time it was.
Stumped many people I know, most common answer was “the first one”. A pilot buddy of mine says airports operate on Zulu time or Greenwich so it has no effect on scheduling to them

That's only if all regions of the world were consistent with their times set relative to Zulu. Time changes make a huge difference on airline/airport scheduling due to certain areas not recognizing DST.
