Make Access Modifier To Public For UpdateStartDate

[sentryadam0000345]

Problem Statement

In some rare cases we aren't ready to use sentry yet but would like to start a trace. Updating end date is enough right now, can still construct whatever length we want though it would be nice to be able to set the start/end to the actual times something happened.

Specifically, this is in regards to overriding the duration value of an event. In particular, overriding the duration value for a custom Performance Span.

Solution Brainstorm

It seems like the change here should be fairly easy. Just change the access modifier to public from private like it is set for updateEndDate.

Here are the relevant lines in the SDK that I found that would need to be looked at/changed:

We'll discuss implications and update here.

Would it also suffice, if we allow setting the start date when starting a span?

[zsperske]

Yes that would work too!

In the meantime this could be solved using beforeSendTransaction.

In v8 of the Java SDK SpanOptions.setStartTimestamp can be used to set the start time of a span or transaction when creating it.
