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()
