This should be a complete sentence, starting with a capital letter and ending
with a full stop.

Make the methods public and remove the friend declaration. We only mark methods
internal to a class as private.

[bartfab (slow), 2013/10/24 13:11:02]

- Put the * on the data type, not the argument name.
- Mark the constructor as explicit.

Put the * on the data type, not the member name.

[bartfab (slow), 2013/10/24 13:11:02]

- Use base::TimeTicks instead: base::Time changes when the timezone or the clock
is adjusted. base::TimeTicks is immune to such changes.
