This exploit will not work on RB03, because there is an additional check for the region:

function setSysTime(time, tzone, index)
    local ccode = XQCountryCode.getCurrentCountryCode()
    local tz = nil
    if TIME_ZONE[tzone] then
        tz = TIME_ZONE[tzone][index + 1]
    end
    if "CN" ~= ccode then
        tz = tzone
    end
    
    if tz and not XQFunction.isStrNil(tzone) then
        .... 
        local isMeshCap = XQFunction.isMeshCap()
        if isMeshCap then
            ...
            XQFunction.forkExec("/sbin/whc_to_re_common_api.sh action \'" .. j_msg .. "\'")
        end
    end
end

But on router RB01, this exploit can work, but you must set whc_cap mode.
I do not know how to achieve this, since I do not have a second device that supports the Xiaomi-Mesh.

P.S.: Device RB06 is in whc_cap mode by default. I even found a place in the code where this is set.
