--- Comment #1 from Jonathan M Davis <issues.dlang@jmdavisProg.com> ---
This is just life with integral types - especially when they're the same size but have different signed-ness. If you want to convert to long from ulong and have it check for overflow, then use std.conv.to!long on the number before constructing a Duration from it. It's quite clear from the signature of dur and its aliases that it takes a long, not a ulong, and always checking for overflow would add overhead for something that happens very rarely. std.conv.to already makes it easy for the programmer to check if they care.
