Inaccurate timing for C# on TSORT

I was trying to beat the fastest java and C# solutions using GO for TSORT. ( https://gist.github.com/robert-king/4fd0818a4ef6c601541a )

However I found that the fastest overall solution was C# ( http://www.codechef.com/status/TSORT?sort_by=Time&sorting_order=asc&language=All&status=15&handle= )

I thought - how is it possible that C# is faster than everyone else even C & C++? So I submitted the C# code and it took 5 seconds instead of 0.09 seconds. Is this a bug with the timings for TSORT? It’s a little misleading especially since lots of new comers use TSORT as a starting point for fast IO etc.
