3// chrono has a slightly awkward API that returns Option<T> in
4// a few cases; for small constant values it makes the call site
5// more complex, especially because the internally panicking variants
6// of the constructor methods are now deprecated, forcing the call
7// site to translate to an error inline or otherwise expect()
8// the error away.
9// This little crate exposes a few constants for infallible cases
10// and wrapper functions that explain the error condition for the others.
