Specifically: https://developers.google.com/url-shortener/v1/url the urlshortener.get returns fields like twoHours, day, week for stats. When does day get reset or which timezone is it calculated from?
I believe those are are all relative. As in day
is the 24 hours leading up to the time of the request. I just did a quick test by clicking on a shortened URL at 10:45am and the click showed up immediately on the graphs.
