Get 24-bit fixed-length sequential code. Used to generate sequential codes with dates. The first 8 bits are the year, month and date. The 9th bit is the microservice designator and takes values in the range 0-15 (displayed as hex 0-9A-F). The 10th bit is the machine designator and takes the value range 0-15 (displayed as 0-9A-F in hexadecimal). The last 14 bits are the sequence codes. Example: 20211202AB10098259438592
