Well, stopwatch functionality could be quite useful completely separately from 
anything representing a date and time, so if you have something good, and it 
doesn't have licensing issues, I'm all for having it in Phobos. High precision 
timers can be quite useful.

As for the date and time functionality, I started on an implementation shortly 
after my initial question yesterday, and I already have more functionality than 
std.gregorian has completed, though I still have a ways to go. I've never looked 
at the Tango stuff, so if what I do is acceptable, it won't have the same issues 
that yours unfortunately did.

When I have something complete enough to be properly useable (though probably 
not with all of the functionality that we'll eventually want), I'll post it 
here. I hope to have that within a few days, if not sooner. As it is, I'm likely 
going to have to implement something similar in C++ for work one of these days 
soon anyway, so that our newer products won't have the same time issues as the 
old ones. Historically, we've had to fix time-related bugs just about every time 
DST rolls around.
