<@U02NBMHMJ9L> do you have more insights on this

Hey <@U03DU6PT5LZ>,
`timestamp` is inserted with `span.startTime`
So `timestamp` column refers start time of span
Check this line on our collector: <https://github.com/SigNoz/opentelemetry-collector-contrib/blob/56e9e96015b99a60174c6fbbd63780c675ca4623/exporter/clickhouseexporter/writer.go#L146>

Thank you <@U02NBMHMJ9L>! I thought is was just timestamp..
