It’s possible when you create an AVD, and add a text field,  
at “Reflect” \> select ‘Chronograph’,  
and select the elapsed or remaining time of a timer.  
Now select that textfield as status indicator.

BLL expression:

```auto
time('D hh:mm.ss', $value)

```

##### About the returned time format:

`D` is for days, `DD` is also possible for timers with a duration of \>10 days  
When it’s below an hour, just use `'mm:ss'`or `'mm.ss'`  
Want to show only seconds? This is the timer value unit, so no need for a _time()_ expression;  
just enter: `$value`

This is possible as well, by additionally using the neat DataVista widget:

Looks much better 💃
