Trace Span startTime Precision Recorded in Milliseconds

When creating a new span with the default options like tracer.startSpan() , the time precision of startTime is truncated to milliseconds, as shown in the image below.

Trace libraries in other languages (Go, C#) support up to microseconds.

This is a peculiar behavior that only occurs when using JavaScript.

Additionally, another strange point is that endTime is recorded up to microseconds.

• [x] This only affects the JavaScript OpenTelemetry library
• [ ] This may affect other libraries, but I would like to get opinions here first
