Method Details

nanosFromTimestamp

public static long nanosFromTimestamp(LocalDateTime dateTime)

Converts a LocalDateTime to nanoseconds since the Unix epoch.

The LocalDateTime is assumed to be in UTC timezone for conversion purposes. When decoded back to LocalDateTime, the timezone information will not be preserved.

Parameters:

dateTime - the LocalDateTime to convert

Returns:

nanoseconds since the Unix epoch

nanosFromTimestamptz

public static long nanosFromTimestamptz(OffsetDateTime dateTime)

Converts an OffsetDateTime to nanoseconds since the Unix epoch.

The timezone information in the OffsetDateTime is preserved during conversion.

Parameters:

dateTime - the OffsetDateTime to convert

Returns:

nanoseconds since the Unix epoch
