Hi,

I’m&nbsp; able to capture spans with Oneagent.  
However,&nbsp; in my app I try to set a defined time for the spans:

Span span1 = spanbuilder1.setStartTimestamp(timestamp1.getTime(),TimeUnit.MILLISECONDS).startSpan();  
span1.end(endtimestamp1.getTime(), TimeUnit.MILLISECONDS);

However, on the PP I see the recorded times.  
Am i doing something wrong or is this feature not yet available ?

Daniel

Hi&nbsp;Daniel,

Actually custom timestamps are not supported, but support for this is on the roadmap.

Hi Harry,  
Really appreciate your answer, I’ve been busting my head over this!

May I ask - is this true for both Oneagent and the Trace Ingest API?

This limitation only applies to OneAgent/OpenTel integration at the moment.

For Trace Ingest, custom timestamps are supported (assuming the the used OpenTelemetry SDK supports it, which is usually the case).
