Why is my Winsock doing this??????

Please help! I cannot find a solution for this, partly because it does not always occur. Ok, here is my problem, I have an app that opens a winsock connection to grab the time from a server at port 13. It seems that at some times, when the getdata line is called, instead of returning a string of data (i.e "Thurs May 20, 2001 12:05:45...") it returns no data, zip nada zilch. The weird thing about this is that it does not always happen. The pattern seems to be when the user requests it for the first time, but I have seen it happen at other times, though. So, you see my predicament regarding trying to narrow down the problem.

Any more info on winsock connections or input will be greatly appreciated. Thanks in advance.
