Yes I think you are correct. I posted when I was in Brisbane which doesn’t have DST but since I had ‘set time zone automatically’ enabled in Windows that accounts for the discrepancy.
Having said that I think this is still an issue for the Dynamo team. I understand that Dynamo can run in multiple host applications and not all of them needs or will have a georeferenced project. But the description of the node is not clear that it uses Windows date/time instead of Revit’s. We should have the ability for both. It is not really practical to change the Window settings to match the Revit project, shut down Revit, open Revit and re-run the Dynamo script.
@JacobSmall @Racel_Williams @Zach_Kron is this something that can be adressed in a future version of Dynamo for Revit?
