I have been all over the \'tubes and I can\'t figure this one out. Might be simple.
The following String.Format call:
String.Format
return dt.ToString
I don't like the C# @ strings unless I really have to use them so I would actually go with this.
return dt.ToString("MMM d \\'yy 'at' H:mmm");
It's just a preference though for which you find easier to "read".
