Hello,
Trade.EntryDateTime in 5.28.1 reports date in 64 bit format
instead of 32 bit expected by DateTimeToStr.
Will be fixed in next beta.
Best regards, Tomasz

Subject: [amibroker] Re: Help with
converting DateTimes in CBT
Really
weird that it works for you, and not for me. I can't think of any other
setting that could possibly affect this. And it's not just dumping to file
that does not work. As a test, I can't add a datetime as a custom metric to
the backtester report. The string shows up as "Invalid DateTime". If I try to
add it as a number, it shows up as
"0.0":
EntryDate =
Trade.EntryDateTime;
EntryDateStr =
DateTimeToStr(EntryDate);
Trade.AddCustomMetric(
"EntryDate" ,EntryDateStr );
Of course I know
that the entry date column already exists in the backtester report. I'm just
doing this as a test, after the dump to file did not work.
Is this a
possible bug in AB 5.28.1?
I don't recall ever having any problems
with DateTime conversions in previous versions, and I've done stuff like this
before.

I had changed my PC system time format to be compatible with some _vbscript_
programs I needed to run. That might be the culprit, although DateTime works
fine within Amibroker itself. It's only when I try to dump to file that it
gets screwed up. > > > > --- In

inconsistent environment settings between AmiBroker generating the date and
whatever you're using to open the generated file (e.g. American form vs.
Australian)? > > > > Mike > > > > --- In
