When I enter a new price for a given day for a security on the NASDAQ via

Are you entering the prices by hand ?
indeed, "via the price editor" (source=user:price-editor in the prices
table)
OK, I'm not seeing the problem. Isn't gnc behaving as expected ?
But John R says "that's an absolute time anchored in the market's time
zone, not the user's. " which leaves me puzzled as for the example above
on
the NASDAQ it uses European time (i.e.my local time) not NASDAQ time. But
maybe when using the Perl finance quote program, there is a more complete
time information (incl the correct market timezone).
If you are entering the prices yourself then it seems sensible to me the
time is when you made the entry rather than the market's time.
yes, indeed. John's comment made me doubt ...
if I use the price editor for today (source=user:price-editor), I get as
date 2012/02/12 23:00:00 (because I am in UTC+1)
if I edit a transaction for today on that commodity
(source=user:xfer-dialog), then I get as date 2012/02/13 10:59:00 (which is
Oh, ffs. Sebastien are you really entering prices from 5 years ago ???
by hand ???
and wondering about the fucking time ???
I have respect for you. Please have some respect for yourself and how
other people regard you.
the post_date of the transaction which uses GnuCash "neutral time" concept.
I haven't tried yet via the Finance:Quote as it doesn't install easily
under my setup (windows, non admin) but I would be curious to see what ends
up in the date column in this case.
If I look at my raw xml file F::Q gives me
===
<price:time>
<ts:date>2018-02-09 12:00:00 +0000</ts:date>
</price:time>
===
which is correct, does everyone get something different ?
I say, if you are entering by hand it *should* be the entry time not the
market time.
Also, unless you have a special arrangement with a broker, most people
don't get a market price, it will be a bit under or over so the market
price is just for reference once you include tx costs, etc.
Anyway, my question was to understand the reasons of the encoding of a
day/date as an instant/datetime, reasons that are still a bit obscure
(except legacy issue)
For most purposes it shouldn't matter. The prices db is independent of
the actual transactions, it is used for working out the value of stuff and,
as I am sure you are aware, the value of commodities changes every minute
and second ... gnc is *never* going to keep up with that sort of price
change.
In retrospect it may be thought that the design mistake was including a
time in the price db at all :)
That's exaclty my point ;-)
OK, Mr SdM are you saying the point is that there shouldn't be a time at
all ?
If so I think John said he'll get around to fixing that as and when. I
don't see the point in arguing about an hour or two 5 years ago which
seems to be what you started :(
