So I just discovered this strange issues where the Folderitem.ModificationDate and CreationDate are returning times about 5 minutes into the future. This is happening for me on Mojave with Xojo 2019r3 (it worked fine in 2019r1)
I haven't tested windows yet, but I had to switch to the MBS Plugins which are working properly to get the correct times.
Feedback 558811: Feedback Case #58811
I left a sample project in Feedback, but was wondering if anyone else had experienced this issue.
Created Xojo: 3:46:36 PM
Created MBS: 3:42:52 PM
Modified Xojo: 5:59:30 PM
Modified MBS: 5:55:46 PM
Edit: I just tried Folderitem.CreationDateTime and it returns the wrong time as well.
