All Implemented Interfaces:

Comparable<TimeUuid>
```
public class TimeUuid
extends Object
implements Comparable<TimeUuid>
```
A UUID implementation. It supports creating version 7 UUIDs, which are time-ordered. See also draft-ietf-uuidrev-rfc4122bis-00 Unlike java.util.UUID, the comparison is unsigned, so that the string comparison yields the same result.

    Returns:
    
    counter part
  - getRandomPart
```

```
    Get the next timestamp (in milliseconds) and counter. The lowest 12 bits of the returned value is the counter. The milliseconds are shifted by 12 bits.
    
    Parameters:
    
    now - the milliseconds
    
    lastMillisAndCount - the last returned value
    
    Returns:
    
    the new value
