Class TimeTCPClient
public final class 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.

DEFAULT_PORT
public static final int DEFAULT_PORT
The default time port. It is set to 37 according to RFC 868. **
- 37
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

TimeTCPClient
public TimeTCPClient()
The default TimeTCPClient constructor. It merely sets the default
port to DEFAULT_PORT
.
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.
- A Date value containing the time retrieved from the server
converted to the local timezone.
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.
- The time value retrieved from the server.
