How to truncate the time on a DateTime object in Python?
...our years later: another way, avoiding replace
I know the accepted answer from four years ago works, but this seems a tad lighter than using replace:

invoked.
You can use beforeExit to test asynchronous functions.

How can I pass a member function where a free function is expected?
...and call your member through a forwarding function which obtains an object from the void* and then calls the member function.
In a proper C++ interface you might want to have a look at having your function take templated argument for function objects to use arbitrary class types. If using a templat...
Get the name of an object's type
... = 1;}
function b() { this.bar = 2; }
b.prototype = new a(); // b inherits from a
Things now don't work as you might expect them to:
var f = new b(); // instantiate a new object with the b constructor
(f.constructor == b); // false
(f.constructor == a); // true
