Sequential guid generator.
Format is as follows:
counter | process id | machine id | unix epoch time | empty | |||||||||||
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
- unix epoch time - number of seconds since 01.01.1970, big endian order
- machine id - first 4 bytes of MD5 hash taken from machine name, order 8-9-6-7
- process id - first 2 bytes of process identifier, order 4-5
- counter - auto-incrementing overflow integer counter, start value is randomly generated during process startup, big endian order
