Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    date time to number and back in xbasic

    Hi

    In Javacript I can use the following function to get a numeric value of the current datetime

    var d = new Date();
    var rdatetime = d.getTime();

    I now have this value in a field in table and I want to process it in Xbasic back to a readable datetime string.

    In javascript I would do the following

    var dn = Date(rdatetime);

    I can't seem to find the equivalent function in xbasic.

    What am I missing?

    Thanks
    tom

    Re: date time to number and back in xbasic

    i am not sure there is any function like that in alpha.
    the javascript epoch is 01/01/1970, the alpha julian date jdate and jtodate epoch runs further back and yields only date number.
    you may have to write your own function or if you can use jdate in alpha itself then
    assign date value to store that and convert back to human readable format using jtodate function.

      here is a function that you can play with and see if it works out for you:
      Code:
      FUNCTION alphaEpoch AS D(dNumber as N)
      dim jday as n
      jday = dNumber/(24*60*60*1000)
      alphaEpoch = jtodate(2440588+jday)
      END FUNCTION
      now pass that number to this function and see if it converts properly.

        You really just to change your milliseconds to seconds and add that to 1970. Remember that .getTime() uses UTC, so you can use the XBasic function getTimeZoneOffset() to get the number of hours difference and adjust your calculation by it.

        Javascript

        Code:
        var d = new Date();
        var rdateTime = d.getTime();
        nbrSeconds = rdateTime / 1000.0;
        nbrSeconds = parseInt(nbrSeconds);
        
        {dialog.Object}.ajaxCallback('','','convertSeconds','','nbrSeconds='+nbrSeconds);

        XBasic

        function convertSeconds as c (e as p)

        debug(1)


        dim startDate as t
        dim endDate as t
        dim nbrSeconds as n = val(e.nbrSeconds)
        startDate = ctodt("01/01/1970 00:00:00 am")

        dim utcDiff as n
        utcDiff = gettimezoneoffset()
        utcDiff = utcDiff*60*60

        nbrSeconds = nbrSeconds + utcDiff

        endDate = startDate + nbrSeconds


        end function

        I'd bet there's an XBasic function to do this... but... it's simple enough.

          Hi David / Gandhi

          These are both good suggestions and both were areas I was looking at. I need the time portion of the date so David what your proposing works best. I had been passing date time as a string from android phones via a text file to xbasic, but depending on how the user was setting the format for date on the phone I was getting different formats. Now I can just pass through this numeric string .....although I do have to pass in the correct timezone offset from the phone or I'll end up with the Server offset.

          Thanks,
          Tom

            Right... nice that it's the same function name... coincidence??? I think not...

            d.getTimezoneOffset();

              Hi. Does anyone know how to create an Epoch timestamp in milliseconds? I'm using time_to_unixtimestamp(now()) but it's not giving me what I'm looking for.

                I knew I'd seen that before... no idea what it's name was... could not find it again.

                Is doing the math for milliseconds not giving you what you need?

                  as it turns out there is a function
                  unixtimestamp_to_time function
                  you can just pass that number to that function.
                  you may take a look and see if that fits your need.

                    thanks for the replys. The solution for what I need is time_to_unixtimestamp(now(.t.)).

                      So you wanted UTC Epoch time in seconds. That's a nice simple solution... thanks for posting.
