Galera UUID

From  To    Length  Content
----- ----  ------- ---------------------------
 0     31    32     Bits 0-31 of Coordinated Universal Time (UTC) as a count of 100-nanosecond
 		    intervals since 00:00:00.00, 15 October 1582, encoded as big-endian 32-bit
		    number.
32     47    16     Bits 32-47 of UTC as a count of 100-nanosecond intervals since 00:00:00.00,
		    15 October 1582, encoded as big-endian 16-bit number.
48     59    12     Bits 48-59 of UTC as a count of 100-nanosecond intervals since 00:00:00.00,
		    15 October 1582, encoded as big-endian 16-bit number.
60     63     4     UUID version number: always equal to 1 (DCE UUID).
64     69     6     most-significants bits of random number, which generated from the server
		    process PID and Coordinated Universal Time (UTC) as a count of 100-nanosecond
		    intervals since 00:00:00.00, 15 October 1582.
70     71     2     UID variant: always equal to binary 10 (DCE variant).
72     79     8     8 least-significant bits of  random number, which generated from the server
		    process PID and Coordinated Universal Time (UTC) as a count of 100-nanosecond
		    intervals since 00:00:00.00, 15 October 1582.
80     80     1     Random bit ("unique node identifier").
81     81     1     Always equal to the one ("locally administered MAC address").
82    127    46     Random bits ("unique node identifier"): readed from the /dev/urandom
		    or (if /dev/urandom is unavailable) generated based on the server process PID,
		    current time and bits of the default "zero node identifier" (entropy data).
