Lasse R.H. Nielsen 0f0f045128 Fix bug in Duration.toString.
The `toString` used the sign of `hours` to get a leading `-`
when the duration is negative. However, a negative duration of
less than one hour would therefore miss out on the sign,
because `-0` is not an integer.
Now handles sign explicitly.

Fixes #48841.
