Riddle me this?? Daylight savings time
 

Anyone good at math?
I’m giving family a ride to the airport this Saturday (Nov 4th) evening, their flight is at 01:40 am PST on Sunday (Nov 5th) The clocks fall back one hour at 02:00 am PST on Sunday (Nov 5th). In effect it will be 01:40 am twice exactly 60 minutes apart.
Which 01:40am is the flight at? The 1st or the 2nd time?

Ps, the flight itinerary makes no mention of this nor does it denote PST or PDT

The first time.

I would take a gamble and show up for the second time. No sense waiting around that extra hour if you are wrong and come too early.:wink:

If by family you mean mother in law I would go with the first 1. No sense in keeping her around the extra hour, and if you take the gamble and miss the flight....... she stays even longer :lol:

If it's a flight departure I'd go with the earlier option.

Kind of annoying they didn't specify PST vs PDT. Might be worth calling to confirm. But the safer bet in any case is get there early.

Oh I didn't realize it was your mother-in-law. I would go with the earlier option might also get her there extra earlier because in all the confusion of the time changes the airline might screw it up and leave an extra hour early.

So did you go for the 1st or 2nd 1:40am?

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.
