Has anyone noticed any difference in campaign delivery after changing the ad account timezone? I recently changed the timezone on an active campaign and the spend pattern looked different afterward. Not sure if it was related or just a coincidence.

Curious if anyone has tested this or tracked the impact properly.

I havent seen a major impact, but timezone changes can affect daily reporting and spend timing. I prefer setting it correctly before launching.

Time zone differences can make an impact on the reporting window rather than on the delivery itself, in particular, if the campaign uses hourly data for its execution with automatic rules applied. The best way to measure the effectiveness would be to look at several days before and after the change of spending.

Time zones don't significantly impact campaigns, but sometimes campaign spending will be higher than usual towards the end of the day. Therefore, it's best to set them up correctly from the start, as adjustments will affect the campaign's target audience.

honestly i changed the timezone once and i didn't notice any major difference and also i think other things like audience or competition usually have a bigger impact on this.
