You're correct with the $dile identifier
It replies 0 with every command you give.

But then again

i used the idle property of $nick(#,nick)

which,( the command given in the channel), returns the idle time of that person in that specific channel;
since that nick can also be yourself, my testing results show me my own idle time in that specific channel
