Question

In particular, is there any difference between these two lines in terms of their outcomes:

File.SetCreationTime("foo.txt", DateTime.UtcNow);
File.SetCreationTimeUtc("foo.txt", DateTime.UtcNow);

Perhaps File.SetCreationTimeUtc("foo.txt", DateTime.Now) is just another way of doing File.SetCreationTime("foo.txt", DateTime.UtcNow)?

The same question applies to File.SetLastAccessTime() vs. File.SetLastAccessTimeUtc() and File.SetLastWriteTime() vs. File.SetLastWriteTimeUtc()

Answer 1

The first one will set the wrong time because it is expecting a date expressed in your local time zone.
