Nanosecond precision is preserved by passing nanoseconds as a separate
argument to the constructor. If nanoseconds are given, any subsecond
precision in the timestamp will be overridden when encoding the timestamp
as a string.
Example:
use Google\Cloud\Spanner\SpannerClient;
$spanner = new SpannerClient(['projectId' => 'my-project']);
$timestamp = $spanner->timestamp(new \DateTime('2003-02-05 11:15:02.421827Z'));
// Timestamps can be cast to strings.
echo (string) $timestamp;
