Problem passing --static-time to 'start'

When trying to start daml with static time, I’m running into problems:

luciano@DA-Luciano:/tmp$ daml new foo
Created a new project in "foo" based on the template "skeleton".
luciano@DA-Luciano:/tmp$ cd foo
luciano@DA-Luciano:/tmp/foo$ daml start --sandbox-option --static-time
Compiling foo to a DAR.
Created .daml/dist/foo-0.0.1.dar
Waiting for sandbox to start: 
Error: Option --static-time failed when given ''. Static time mode (`-s`/`--static-time`) and wall-clock time mode (`-w`/`--wall-clock-time`) are mutually exclusive. The time mode must be unambiguous.
Try --help for more information.

Not quite sure what this means … especially the when given ''. Is this a bug? Seems to work when running the sandbox directly though:

Initialized sandbox version 1.10.0-snapshot.20210209.6265.0.19bf4031

Hi @Luciano. The default daml.yaml contains the following section

sandbox-options:
  - --wall-clock-time

which conflicts with the CLI option you’re passing. You have to remove it from daml.yaml.

Arguably the CLI option should overwite the config file but for various reasons that’s not what happens right now.
