All units seconds and greater are spelled out completely. All sub-second units
are abbreviated. That's by design.

We _could_ make it so that there are multiple names for each unit type, but
then that gets messy - both in terms of code and in terms of people having to
decipher template constraints. It's just cleaner to accept one specific string
for each unit type. So, I think that having multiple is ultimately a bad idea.

Changing the unit strings would break code for little gain IMHO. And going for
names as short as you suggest is error-prone. It's already bad enough that
msecs, usecs, and hnsecs are as similar as they are. The functions that the
unit strings are used with are exactly the kind of functions where it's often
easy to not notice a bug when the units are slightly off. So, making them even
less distinct would _not_ be a good idea as far as I'm concerned.
