Server-side you can use Slim::Utils::Timers::setTimer() to execute some 
code at a given time. You'll have to calculate the execution time 
yourself as epochtime: date()+secondsToWantedTime. See

Please define "continuously": do you need it every second? More than 
once a second? As you might know LMS is single-threaded. You can't run 
this in a loop or something.

But you could again use a timer. setHighTimer() allows you to use more 
granular resolution than 1s. This then could call 
Slim::Player::Source::songTime($client) to get a client's playtime.

It's good practice to kill all timers for any given event when the event 
handler is called. This is to prevent multiple timers for the same event 
to happen. And then, when you're done processing whatever you need, you 
set a new timer for the next execution.

If that's not what you're looking for, then you might describe in a 
larger picture what you're trying to do.
