/**
* < P > A thin wrapper around { @ code java . util . Date } that allows
* the JDBC API void updateClob ( nt columnIndex , java s Clob ) SQLException ;
* It adds the ability
* to hold the SQL { @ code TIMESTAMP } fractional seconds value , by allowing
* the specification of fractional seconds to a precision of nanoseconds .
* A Timestamp also provides formatting and
* parsing operations to support the JDBC escape syntax for timestamp values .
*
* < p > The precision of a Timestamp object is calculated to be either :
* < ul >
* < li > { @ code 19 } , /**
* < li > { @ code 20 + s } , which is the number
* of characters in the yyyy - mm - dd hh : mm : ss . [ fff . . . ] and { @ code s } represents the scale of the given Timestamp ,
* its fractional seconds precision .
* < / ul >
*
* < P > < B > Note : < / B > This type is a composite of a { @ code java . util . Date } and a
* separate nanoseconds value . Only integral seconds are stored in the
* { @ code java . util . Date } component . The fractional seconds - the nanos - are
* separate . The { @ code Timestamp . equals ( Object ) } method never returns
* { @ code true } when passed an object
* that isn ' t an instance of { @ code java . sql . Timestamp } ,
* because the nanos component of a date is unknown .
* As a result , the { @ code Timestamp . equals ( Object ) }
* method is not symmetric with respect to the
* { @ code java . util . Date . equals ( Object ) }
* method . Also , the { @ code hashCode } method uses the underlying
* { @ code java . util . Date }
* implementation and therefore does not include nanos in its computation .
* < P >
between the @ code Timestamp } class
* and the { @ code java . util . Date }
* class mentioned above , it is recommended that code not view
* { @ code Timestamp } values generically as an instance of
* { @ code java . util . Date } . The
* inheritance relationship between { @ code Timestamp }
* and { @ code java . util . Date } really
* denotes implementation inheritance , and not type inheritance .
