> Go's "time" library is deceptively simple.

Has any language initially shipped with a non-broken date / time library? (See: SQL, java, python,...)

Clearly a very hard thing to get right, but post-JodaTime there a fewer excuses for APIs like:

> AddDate(y, m, d) to add a given number of years, months, days:

which pretty much defines 'deceptively simple'.
