Hi David,
Thank you for your confirmation.
Actually we have not had any plan to support timezone at data source level up to now (since timezones are a complicated beast, and different customers will definitely have different use-cases). Our upcoming plan is to release the Organization & Dashboard-level timezone settings first, then collect more feedback and use cases from all of you (to make sure that we’re on the right track).
Therefore, it’s difficult for us to confirm that we will support the data source-level timezone setting right now. However, we have already added your request to our backlog, and will get back to you if there is any further update on it.
We just want to let you know that our issue is really important to us, and we will try our best to enhance your working experience with our product in the future. Again, we really appreciate your patience and understanding.
