Currently I'm working on Instana Analytics. I have URL in form:

https://instana.io/#/.........timeline.ws=172800000&timeline.to=1749506400000&timeline.fm=1749506400000&timeline.ar=false

My question is how work "timeline" in this link.

I was thinking that maybe that is Unix Timestamp, but I don't understand how it work. 

`timeline.ws` is proper Unix Timestamp, but it points to 1975. `timeline.to` and `timeline.fm` is too long for Unix Timestamp.

It's like we have `timeline.ws` which point to some date in the past and `timeline.to` and `.fm` is adding time to `timeline.ws`?

But in what form are `timeline.to` and `.fm`? It's no Unix Timestamp because it's too long.

I would like to understand, based on what this timeline is working. I would like to write properly value to this timelines field and this link would open Analytics in proper range time in Instana.

Hi Michał,
It can be tricky at the beginning if you haven't read things from the Instana OpenAPI but here is an example based on your URL parameters:

timeline.ws = windowSize

timeline.fm = From

timeline.to = To

integer <int64>
Timestamp since Unix Epoch in milliseconds of the end of the time window.

Your to is the same as from: Monday 9 June 2025 22:00:00

timeline.ar

Is the "Live button" autorefresh.

In your URL, you need to define your from and to properly to get the data from the timeframe you want.

I hope this helps.
