There are a bunch of routines in druntime that could really use a structured

most of these) and I'm trying to work out the best way to do this.  In Tango, 
the decision was to have the routines all accept a long value that is the same 
resolution as the tick count from TimeSpan, which is why everything currently 
works as it does.  I've always hated this and would love to do something more 
structured, but complications arise from possible redundancy or incompatibility 
with std.time.  What I've done for now is duplicate Boost's time_duration 
struct (as TimeDuration) into core.time, and I'm looking at using this for 
Thread.sleep(), etc.  Thoughts?


I thought Tango used a floating point representation of time? (BTW, I think such a representation is a mistake for various reasons.)
