Is your feature request related to a problem? Please describe.

The pdatatest framework currently enforces span comparisons based on timestamps.

Describe the solution you'd like

I would like to be able to ignore timestamps in comparisons.

Describe alternatives you've considered

We use this code to modify the spans:

func ignoreStartTimestamp(traces ptrace.Traces) {
	for i := 0; i < traces.ResourceSpans().Len(); i++ {
		rs := traces.ResourceSpans().At(i)
		for j := 0; j < rs.ScopeSpans().Len(); j++ {
			ss := rs.ScopeSpans().At(j)
			for k := 0; k < ss.Spans().Len(); k++ {
				span := ss.Spans().At(k)
				span.SetStartTimestamp(0)
			}
		}
	}
}

func ignoreEndTimestamp(traces ptrace.Traces) {
	for i := 0; i < traces.ResourceSpans().Len(); i++ {
		rs := traces.ResourceSpans().At(i)
		for j := 0; j < rs.ScopeSpans().Len(); j++ {
			ss := rs.ScopeSpans().At(j)
			for k := 0; k < ss.Spans().Len(); k++ {
				span := ss.Spans().At(k)
				span.SetEndTimestamp(0)
			}
		}
	}
}
