You can get the time zone, or at least the zone offset, by using "the
internet date".

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 function, but that
assumes you already know the time zone. Although LC has a Time Zone
library, I haven’t found any documentation explaining how an app can find
out which Time Zone it’s actually in. In fact my app doesn’t care that
much, so will stick to UTC.
The documentation around all this needs a bit of tidying up, IMHO.

If you only use a date and convert it, dateItems will assume the time to
be midnight on that particular date.

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
put t1
You get e.g.
2020,10,29,11,40,0,5
i.e if you specify the date, you only get the date; but if you specify the
time, you get the date thrown in. I could not deduce this from the
Dictionary, but maybe I am just poor at reading what it says.

Thanks Tore - I had forgotten the existence of dateItems. That of course
will do the trick. BTW I was trying to create dates in standard UTC format,
and now I can.

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 day of the week where Sunday is day 1, Monday is day 2, and so
forth
All according to the Dictionary.
To be sure that any valid date format is recognized as a date when you read
in the date you will like to convert, it is best to ask for the system date
or set the useSystemDate to true, as this will make all valid date formats
convert to dateItems.

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 force the
format for consistency’s sake, regardless of where in the world it’s being run.
Can it be done?
