As rrq just pointed out on #devuan-infra, this is actually a bug in sysvinit
/sbin/shutdown not parsing the +0 argument.

This was fixed upstream in version 2.98:

sysvinit (2.98) released; urgency=low

    * Fixed time parsing in shutdown when there is a + in front of a 0 time offset.
      Commands with a positive time offset (+1) would work but +0 fails.
      This has been corrected by Arkadiusz Miskiewicz.

Reassigning and setting versions.

I will investigate backporting to chimaera.

Thanks.

Mark
