Method Details

getTime

public String getTime()
               throws IOException

Retrieves the time string from the server and returns it. 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 string retrieved from the server.

Throws:

IOException - If an error occurs while fetching the time string.
