Constructor Detail

SecondTimestamp

public SecondTimestamp()
Construct a SecondTimestamp with 'now' as the timestamp. The Java runtime currently goes down to milliseconds, so these are a bit inaccurate.


SecondTimestamp

public SecondTimestamp(long ts)
Construct a SecondTimestamp from a number of seconds.


SecondTimestamp

public SecondTimestamp(long seconds,
                       int nanoseconds)
Construct a SecondTimestamp from a number of seconds and a number of nanoseconds.


SecondTimestamp

public SecondTimestamp(java.util.Date date)
Construct a SecondTimestamp from a Date object. The Java runtime currently goes down to milliseconds, so these are a bit inaccurate.
