Example 5 with Endpoint

use of zipkin.Endpoint in project zipkin by openzipkin.

the class SpanStoreTest method correctsClockSkew.

   * Basic clock skew correction is something span stores should support, until the UI supports
   * happens-before without using timestamps. The easiest clock skew to correct is where a child
   * appears to happen before the parent.
   *
   * <p>It doesn't matter if clock-skew correction happens at store or query time, as long as it
   * occurs by the time results are returned.
   *
   * <p>Span stores who don't support this can override and disable this test, noting in the README
   * the limitation.
