Two options exist:

Use $$ENV instead of $ENV to add to ~/.irssi/startup config file.

/format timestamp {timestamp %%H:%%M:%%S} 

Configure join/leave Messages to appear in grey on black

From Copy /usr/share/irssi/themes/default.theme to ~/.irssi/default.theme then edit settings as follows:

channick_hilight = "%K$*%K";
chanhost_hilight = "{nickhost %K$*%K}";
channick = "%K$*%K";
chanhost = "{nickhost %K$*}";
