How to get the number of days of difference between two dates on mysql?
...-14 11:00:00');
returns 1
select timestampdiff(DAY, '2016-04-13 11:00:00', now()); returns how many full 24h days has passed since 2016-04-13 11:00:00 until now.

... void foo(T const&); and void foo(T&&);.
With that in mind, I now wrote my valued constructors as such:
class T {
U u;
