B4J Code Snippet Set File Modified Date using JavaObject

DateTime.DateFormat = "yyyy-MM-dd"
DateTime.TimeFormat = "hh:mm a"
Dim LastModifiedTime As Long = DateTime.DateTimeParse("2026-01-20", "10:05 pm")
Dim jo As JavaObject
jo.InitializeNewInstance("java.io.File", Array(File.Combine(File.DirApp, "dummy.txt")))
jo.RunMethod("setLastModified", Array(LastModifiedTime))

Edit: Sorry, just found this code snippet actually already existed

File.Copy without changing the time ?

File explorer copies files without changing their "last modified" property, File.Copy does change it. Is there a way to copy a file without modifying its "last modified" property ? I've found this link showing how you can set this property in java...
