Method Detail

• getTime

  public long getTime()
               throws IOException

  Retrieves the time from the server and returns it. The time is the number of seconds since 00:00 (midnight) 1 January 1900 GMT, as specified by RFC 868. This method reads the raw 32-bit big-endian unsigned integer from the server, converts it to a Java long, and returns the value.

  The server will have closed the connection at this point, so you should call disconnect after calling this method. To retrieve another time, you must initiate another connection with connect before calling getTime() again.

  Returns:

  The time value retrieved from the server.

  Throws:

  IOException - If an error occurs while fetching the time.

• getDate

  public Date getDate()
               throws IOException

  Retrieves the time from the server and returns a Java Date containing the time converted to the local timezone.

  The server will have closed the connection at this point, so you should call disconnect after calling this method. To retrieve another time, you must initiate another connection with connect before calling getDate() again.

  Returns:

  A Date value containing the time retrieved from the server converted to the local timezone.

  Throws:

  IOException - If an error occurs while fetching the time.
