How to: Determine a File's Last Modified Time in Visual Basic
The GetFileInfo method can be used to get a FileInfo object, which contains information about the specified file.
You can use the LastWriteTime or the LastWriteTimeUtc property to get or set the last time the file was modified. LastWriteTimeUtc displays the time in Coordinated Universal Time (UTC). For more information, see Standard Date and Time Format Strings.
