suggest add space or '.' before tss.2 like before tss.1 https://github.com/donnie4w/tklog/blob/bcfe8323e641eac215a9473b42313aaf88d79397/src/lib.rs#L471

        if !tss.1.is_empty() {
            if !time.is_empty() {
                time.push(' ');
            }
            time.push_str(tss.1.as_str());
        }

        if !tss.2.is_empty() {
+            if !time.is_empty() {
+               time.push(' ');
+            }
            time.push_str(tss.2.as_str());
        }
