Citation: >> For instances of maps that are run at "night" it is possible to change the local time of day so that it is easier for a user to see opposing
>> tanks. the - and = keys by default allow a user to change the local time of day. This change does not affect the server.
>>Some servers can enable options that override this ability and force a client to use the server's time of day.
Question: Why it does not work for me? Versions: OS Linux, Bzflag 2.4.2.
I tried on different servers, including my local. Does not work everywhere

Thx
My final goal: I need to set the night permanently (or at least temporarily). It's easier for me to navigate.
