Does anyone else find interest in this, or am I the only one having this
want? Does anyone have a better idea of syntax to do this =E2=80=9Cnegative
interval=E2=80=9D? `11am+-00:30` looks kind of weird, but `-` is already ta=
ken.

Also, I often find myself inputting minutes in those intervals. Do you
think a syntax like `11am+15'` would make sense, instead of
`11am+00:15`, which is less nice to type?

Cheers,
  Leo
