Class TimeTCPClient
java.lang.Object
org.apache.commons.net.SocketClient
org.apache.commons.net.time.TimeTCPClient
The TimeTCPClient class is a TCP implementation of a client for the Time protocol described in RFC 868. To use the class, merely establish a connection with
 
connect  and call either getTime()  or getDate()  to retrieve the time,
 then call disconnect  to close the connection properly.- See Also:

Field Details- 
DEFAULT_PORTThe default time port. It is set to 37 according to RFC 868.- See Also:
 
- 
SECONDS_1900_TO_1970The number of seconds between 00:00 1 January 1900 and 00:00 1 January 1970. This value can be useful for converting time values to other formats.- See Also:

Method Details- 
getDateRetrieves the time from the server and returns a Java Date containing the time converted to the local time zone.The server will have closed the connection at this point, so you should call disconnectafter calling this method. To retrieve another time, you must initiate another connection withconnectbefore callinggetDate()again.- Returns:
- A Date value containing the time retrieved from the server converted to the local time zone.
- Throws:
- IOException- If an error occurs while fetching the time.
 
- 
getTimeRetrieves 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 disconnectafter calling this method. To retrieve another time, you must initiate another connection withconnectbefore callinggetTime()again.- Returns:
- The time value retrieved from the server.
- Throws:
- IOException- If an error occurs while fetching the time.
