+ * * **time_mid**: The middle field of the timestamp, an unsigned 16-bit integer
+ * * **time_hi_and_version**: The high field of the timestamp multiplexed with
+ *   the version number, an unsigned 16-bit integer
+ * * **clock_seq_hi_and_reserved**: The high field of the clock sequence
+ *   multiplexed with the variant, an unsigned 8-bit integer
+ * * **clock_seq_low**: The low field of the clock sequence, an unsigned
+ *   8-bit integer
+ * * **node**: The spatially unique node identifier, an unsigned 48-bit
+ *   integer
