+### `microfortnights`?!  Are you serious?
+(by [Howard Hinnant](https://github.com/HowardHinnant))
+
+Well, kind of.  The point of this article is to illustrate that no matter how crazy your units of time are, this library can handle it, and with style.
+
+If you're dealing with quarter-second durations, or frame-durations of 1/60 second, or whatever, `<chrono>` can build the duration, and this library can format it.  And all with very little effort.  Let's say that you've got a time point consisting of a month, day, year, hour, minute, and microfortnight, just how hard is that to format out into human-readable format?!
+
+Turns out not hard at all.
+
+    #include "date.h"
+    #include <iostream>
+
+    using fortnights =
+        std::chrono::duration<date::weeks::rep, std::ratio_multiply<std::ratio<2>,
+                                                                    date::weeks::period>>;
+
+    using microfortnights =
+        std::chrono::duration<std::int64_t, std::ratio_multiply<fortnights::period,
+                                                                std::micro>>;
+
+    int
+    main()
+    {
+        using namespace date;
+        using namespace std::chrono;
+        std::cout << format("%F %T\n", sys_days{nov/29/2016} + 15h + 13min + microfortnights{35});
+    }
+
+The first thing to do is build your `chrono::duration` that represents a `microfortnight`.  This is best done by first building a `fortnight`, and then multiplying that by `std::micro`.  This will build some weird `chrono::duration` with a period we don't really have to know, but turns out to be not that far off from a second.
+
+To specify a `sys_time` in terms of this weird unit, you just do the usual addition.  But instead of adding `seconds` you add `microfortnights`.  Now it turns out that a microfortnight is _exactly_ 1.2096 seconds (who knew?).  But you don't have to concern yourself with this detail as long as you've correctly defined `fortnights` as 2 `weeks` as above, and `microfortnights` as a `std::micro` times `fortnights` as above.
+
+Now you can just blindly add `microfortnights{35}` to your year/month/day hh::min timestamp as shown above, and ask `format` to format it with `"%F %T"`.  This will output the correct time stamp with fractional decimal seconds to exactly represent `microfortnights`:
+
+    2016-11-29 15:13:42.3360
+
+If this library can do this so easily with something as crazy as `microfortnights`, it can handle your crazy time problem.
