The key to native ads timezones... (3)
I've heard that you MUST have your tracker and traffic source's timezones perfectly aligned.
Why? I recall it has something to do with accurate reporting?
How do you do this? Say you are running in multiple geo's with different zones, what then?
It all depends on what you're tracking and how you track things. Basically you just want to have clarity.
For some people that's through connecting everything to TheOptimizer and only looking at it. For some people it's only looking at
Basically you just want to make sure you have a clear, accurate picture of all your clicks/spend/conversions/stats/etc, but there's no one way to ensure that 
For myself, I pass conversions and view the traffic source as the 'official' stats, but I use Thrive to analyze landing pages/offers/geo's/devices/browsers/etc. I don't continually update Thrive to have correct cpc data though.
It's about the trafficsource(s) timezone, not campaign geo timezone.
When you update your cost for a campaign you want your tracker and source timezone to be the same.
Not a must by any means, just something to adds some clarity to your daily totals when you're running multiple sources with their platforms in different timezones. So you can compare stats in your tracker vs source at times and they line-up.
For optimization purposes you'd want to use a 3rd party API to see actual placement costs instead of averaged CPC cost in your tracker, but most traffic source platforms should do that anyway.
