            <div class="class-description"><p>A timestamp generator that guarantees monotonically increasing timestamps and logs warnings when timestamps
drift in the future.</p>
<p>Date has millisecond precision and client timestamps require microsecond precision. This generator
keeps track of the last generated timestamp, and if the current time is within the same millisecond as the last,
it fills the microsecond portion of the new timestamp with the value of an incrementing counter.</p></div>
