All Implemented Interfaces:

Comparable<TimestampData>
```
@PublicEvolving
public final class TimestampData
extends Object
implements Comparable<TimestampData>
```
An internal data structure representing data of TimestampType and LocalZonedTimestampType.
This data structure is immutable and consists of a milliseconds and nanos-of-millisecond since 1970-01-01 00:00:00. It might be stored in a compact representation (as a long value) if values are small enough.

    Parameters:
    
    milliseconds - the number of milliseconds since 1970-01-01 00:00:00; a negative number is the number of milliseconds before 1970-01-01 00:00:00
  - fromEpochMillis
```
public static TimestampData fromEpochMillis(long milliseconds,
                                            int nanosOfMillisecond)
```
    Creates an instance of TimestampData from milliseconds and a nanos-of-millisecond.
    
    Parameters:
    
    milliseconds - the number of milliseconds since 1970-01-01 00:00:00; a negative number is the number of milliseconds before 1970-01-01 00:00:00
    
    nanosOfMillisecond - the nanoseconds within the millisecond, from 0 to 999,999
  - fromLocalDateTime
```
public static TimestampData fromLocalDateTime(LocalDateTime dateTime)
