Hey Vlad. Last time I did a major API export, there is no eplicit pagination so you have to request no more than the limit on the API. For me that meant calling 1 day at a time, which when coupled with limits on # of calls per minute and per day made exporting a large amount of a data a real PITA. Everything was sorted by timestamp in my export (albeit everything was within the day, but the first things of that day were before the last things that day).
