## org.apache.commons.net
Class TimeTCPClient

    java.lang.Object
      org.apache.commons.net.SocketClient
          org.apache.commons.net.TimeTCPClient

public final class TimeTCPClient
extends SocketClient

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.

Field Detail

### DEFAULT_PORT

    public static final int DEFAULT_PORT

### SECONDS_1900_TO_1970

    public static final long SECONDS_1900_TO_1970

  The 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.

Constructor Detail

### TimeTCPClient

    public TimeTCPClient()

  The default TimeTCPClient constructor. It merely sets the default port to `DEFAULT_PORT` .

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.
