Re: And What About the Internet Date and Time?
Hi Peter, Yes, seconds converted from UTC is the only reliable timestamp. I asked about time zone settings in local machines for display purposes. We may have a timestamp that is absolutely correct but if that is to be displayed for the user in a LiveCard app on their local machine, say as a confirmation or receipt, it will not display the correct time unless the user’s time zone is set correctly.

And What About the Internet Date and Time?
Hello again everyone, Okay, please don’t hate me. I'm still trying to nail down a reasonably accurate system-independent date and time stamp to use in my student client app that will submit and retrieve data from my Mac. I will post a modest enhancement to Stephan Barncard’s excellent returnNISTime function shortly. My question is, How does LiveCode know the local computer’s time zone when we ask for the date in the Internet Date format? My guess is that the computer’s owner has to have set it. And if the person is on the move, it may be incorrect even if it was set at their primary location. Yes?

Redux - Getting the Date and Time From the Internet
Hello everyone, Here is a small enhancement to Stephen Barncard’s handler. If you call the function with the option “report” as in put nistTime(“report”) into field “Date and Time” you’ll get a summary. Set the field’s tabstops to 380 for a nice display. After playing with it, I’ve come to the conclusion that the only correct, or most nearly correct, system-independent timestamp is the seconds as converted from a time server such as NIST. However, even that won’t display correctly in any other date-time format on a local machine if the time zone is set incorrectly. That means that the only display format that is sure to be correct is NIST’s GMT, uncontaminated by local time zone settings. Regards, Gregory function nistTime pOption -- Returns UTC time in RFC-867 (Daytime) format from the NIST -- pOption is array or report /* N.B., The only datestamp that is independent of local system settings is the seconds converted from NIST date and time (see nistSeconds).

Re: Retrieving Date and Time From a Remote Computer
Hi Jacqueline, Yes, the date and time must be embedded in the file. An example would be that of subjects participating in an experiment where the client app is the vehicle running it. The app may be a simple questionnaire or a simulation that tracks their choices and activities. The responses are sent via FTP to the server and aggregated in a file whose format might be something like Subject 8, Date Stamp, Time Stamp, Obs 1, Obs 2, Obs 3, etc. Subject 1, Date Stamp, Time Stamp, Obs 1, Obs 2, Obs 3, etc. Subject 1, Date Stamp, Time Stamp, Obs 1, Obs 2, Obs 3, etc. Subject 2, Date Stamp, Time Stamp, Obs 1, Obs 2, Obs 3, etc. Subject 3, Date Stamp, Time Stamp, Obs 1, Obs 2, Obs 3, etc. Subject 7, Date Stamp, Time Stamp, Obs 1, Obs 2, Obs 3, etc. More complicated experiments might involve subject interactions, where the choice of one depends on the choices of others, so the timing is critical. You might ask, Why not do this on the web using iRev, so that delivery is server-side? The answer is that web deployment is a pain in comparison to a standalone deployment. I’ve done a few experiments on the web using my on-rev account, and I find that a standalone gives me much more flexibility and I can do it in a fraction of the time.

Suppose you had a trial scheme which expired the license after 30 days. The easiest way to defeat that would be to always set the clock back whenever you used the software. But that would be to no avail if you check the RealTime (as I named my function). Also, Windows Clients are sometimes configured to get the date and time from an internal time server running on the network. If that time server service stops functioning and the admin doesn't know it, the time can drift quite a bit aver several weeks. Any app that was critically dependent on knowing the exact time might not work correctly. Someone mentioned that if you were using sql, that you could query the sql server for the date and time. This actually has a real advantage over a time server, as NTP or even HTTP could be blocked by a personal firewall using ports or a blacklist, but no one could firewall off the sql server you need to run your application!

Hi Dave Cragg and Mark Schonewille, Thank you both for your responses. Problem solved with a unexpected fix! I tried all of your suggestions, learned a lot about the various libURL commands, which will be useful in my project, but unfortunately, none solved the problem not being able to download that particular 183 KB file. The FTP log told me the download was complete, indicated the correct number of bytes, and that the socket had been closed. But the variable into which the file had been loaded had zero lines in it and did not appear in the field into which I put it. I tried many other files, some as big as 2 MB, and they downloaded fine and in a jiffy. It then occurred to me that this was the only file created with LiveCode using RETURN to delimit line endings, and that perhaps something gets messed up when it is transferred to the remote Mac server. I went through my old Revolution tips and found an email from you, Dave, from 2005, explaining how to clean line endings. Worked like a charm!!! on cleanLineEndings @pText replace crlf with return in pText replace numToChar(13) with return in pText end cleanLineEndings Thanks again, Gregory ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Questions About LiveCode Apps That Connect to the Internet
Hello everyone, I’m building a standalone for my students. It will allow them to upload quizzes and small assignments to my Mac via FTP as well as participate in various experiments and surveys. I have a few Internet-related questions that I hoping someone can answer. Is there a handler I can include in the stack that would allow it to detect whether the user is connected to the Internet? That would allow me to give them the option of working offline. How can I get the current date and time from either a time server or my remote Mac? I need to timestamp student submissions and want the time coming from one source, not their own machines. What is the best way to catch common FTP errors, such as a file not existing, so that I can relay a message back to the users?

FTP To and From My Mac
Hello everyone, I’ve got my Mac at work running as a server of sorts and would like to be able to read and write files to it via FTP. I used the simple GET URL command below and it worked for a 6 KB file but not for a 200 KB file. get url ftp://username:password@serverAddress/Users/me/Documents/pathToFile” How can I get it working for bigger files? I also tried libURLSetFTPMode “active” but it didn’t get me the bigger file. Also, it would be nice if the date and time could be retrieved from the remote Mac or from a time server, but I don’t know how to do that. Any advice would be much appreciated.

Rev Customer Databased Hacked?
Hello everyone, Have any of you received this message from Heather? Implications? Gregory Dear Gregory Lypny, I need to inform you that over the weekend we experienced an attack on our customer database. Although we caught this very quickly I regret that some information may have been compromised. A small number of accounts were affected, unfortunately yours was one of them. The information concerned includes your name, email address, on-rev username and the server you are hosted on. It does not include your password, or any postal address or billing information. This information alone does not represent a security risk. However, if you have any concerns at all that your password for your on-rev account is not secure, you should change it immediately. cPanel offers a secure password generator that includes numbers and punctuation in a random string, we strongly advise you use this service. We deeply regret this breach of our security procedures. We felt it important to inform you of it as quickly as possible as a precautionary measure. We have already traced and fixed the exploit that made this possible and can assure you that the same error will not happen again in the future.

Part II of Re: On-Rev Web Form Dropping Data
Hi Everyone, Yesterday I posted a long question (sorry about that) concerning data lost from a web form submitted through my On-Rev site, where two students appear to have submitted quiz answers from the same IP address at virtually the same time. Bob Sneidar replied asking whether I had accounted for the possibility that more than one person could sign on to my site from the same IP, and I had said that I have not prohibited that. Well, I have since spoken to the students who submitted blank quizzes, and it turns out that they live together, share a wireless network, and each has her own computer. This probably means that they have their router set to share a single IP address or some such thing. I guess what I should do is revise by sign-in script to disallow multiple sign-ins from the same IP.
