Re: Is the DateFormat read only?

Your code contains a smart quote and an em dash. This works: function fUTCTime local t1,t2,t3 -- this gets the current time and puts it into UTC format, i.e -MM-DDThh:mm:ssTZD put word 5 to 6 of the internet date into t3 -- we are interested in the time and time zone put the

This enhancement request (which from various paths has a 14 year history) is still relevant IMHO: https://quality.livecode.com/show_bug.cgi?id=4636 (It also has a handy suggestion from Mark Waddingham of a function to return "ISO date time" (as the discussions in the report shows, a

Re: Is the DateFormat read only?

Looks like a bug to me. So I’d say yes? I’m pretty puzzled why convert does not work with internet date. It seems a bit of a waste to make the internet date a format that you can only display and not   manipulate? Tests here indicate that converting an internet date to seconds makes no

Re: Is the DateFormat read only?

Thank you Matthias. Those detailed instructions will come in handy for me - when/if I get that far. The problem I mentioned a couple of emails ago in this thread was in the IDE - haven\t yet got as far as doing it on the server. I tested out the TimeZone library with a couple of randomly

Re: Is the DateFormat read only?

Alex, i've posted already some info about how to use the time zone library in Livecode server in my comment to David's post "Aw: Basic question: Time Zone Library". Here it is again and a little bit more detailed. 1. copy the folder com.livecode.library.timezone from the LC extensions folder

Re: Is the DateFormat read only?

Thanks Graham. That does indeed work - on your local system. The issue I am trying to deal with (and maybe it's related to what David is doing) is dealing with time zone issues on a LC web server. If you want to timestamp when some event happens, you can do that as a UTC timestamp using a

Re: Is the DateFormat read only?

I am as confused as anyone else as to what you are trying to do, but just in case, this little function seems to work for me to get the ’standard’ UTC date format which I have to use in my app to put time stamps into GPX files. It apparently produces the correct time zone. Doubtless it could be

Re: Is the DateFormat read only?

I don't think it "strips" the TZ info - it simply ignores it. I think the key phrase is in the dictionary as : *Note:* The *convert* command assumes all dates / times are in local time except for 'the seconds', which is taken to be universal time. So it assume syou date is in local time

Re: Is the DateFormat read only?

Good point. For our situation, hours were enough so I guess I ignored the rest (it was a long time ago and the code is old.) On 10/30/20 3:24 PM, Alex Tweedly via use-livecode wrote: But that will only work for those time zones whose variation from UTC is an exact number of hours. the

Re: Is the DateFormat read only?

But that will only work for those time zones whose variation from UTC is an exact number of hours. the internet date has 4 digits so that it can handle hour and minute variations - you could change   subtract (char 1 to -3 of last word of the internet date) from item 4 of tTime to   put

Re: Is the DateFormat read only?

I have a formatDate() function (not to be confused with dateFormat) that has a few extra formats, one I call sql date for instance which is -mm-dd (and another function for time so I can produce a datetime compatible for SQL databases). I suppose it can be expanded for other formats, but

Re: Is the DateFormat read only?

Jacque Right as usual. I had forgotten about the internet date, if I ever knew. I suppose somewhere there is a little essay about all this but if so it is buried in the LC documentation. The only souci with this format is that it gives the month in alpha, presumably according to the

Re: Is the DateFormat read only?

I believe that when you convert a pure time to dateitems it assumes the current date. The date has no time component so it assumes midnight of the current date. Bob S > On Oct 29, 2020, at 04:04 , Graham Samuel via use-livecode > wrote: > > Just FYI, I think the dictionary is wrong or

Re: Is the DateFormat read only?

I understand it, but the Dictionary is misleading and in one case actually wrong: when it says the ’time’ form gives the seconds - it doesn’t. You need to use the ‘long time’, at least so it seems to me. I have submitted a bug report. I also thought that I could use the ToUniversalTime

Re: Is the DateFormat read only?

If you only use a date and convert it, dateItems will assume the time to be midnight on that particular date. Tore > 29. okt. 2020 kl. 12:04 skrev Graham Samuel via use-livecode > : > > Just FYI, I think the dictionary is wrong or misleading in respect of what > the dateItems does. If you

Re: Is the DateFormat read only?

Just FYI, I think the dictionary is wrong or misleading in respect of what the dateItems does. If you script this in the LC Message Box: put the date into t1 convert t1 to dateItems put t1 You get, e.g. 2020,10,29,0,0,0,5 but if you script put the english time into t1 convert t1 to dateItems

Re: Is the DateFormat read only?

You can convert any given date to dateItems. Then you can use dateItems to present the date in any format you like. A date converted to dateItems will give you the following list of items: the year the month number the day of the month the hour in 24-hour time the minute the second the numeric

Is the DateFormat read only?

A quick test seems to show that the DateFormat can’t be changed by a ‘set’ command. How then can I force a date to be in a given format? I’m really thinking of the difference between US and European dates, i.e d/m/y versus m/d/y Obviously for some types of use, an LC program should be able to
