Hello world,
I am very new to Zorro.
I successfully transferred some of my trading setups from InvestoxPlattform to Zorro, but I am struggling to activate a time-function found in the Zorro manual :

To align some self-made Logfile operations via :

file_append("Data\\ABC-LOG.txt",strf( "\n%s UTC", strdate("%d.%m.%Y %a %H:%M:%S UTC",ldate(0,0) ) ), 0)

the results show up as requested in my Logfile-rows :

16.12.2021 Thu 10:35:17 UTC ...
16.12.2021 Thu 10:35:24 UTC ...

Furthermore I would like to have the available fractional-seconds shown in my Logfile to compare Events more precisely.
In the Zorro manual part __Format Codes - C Programmer's Cheat Sheet__ I found the parameter %S to be able to show fractional seconds :

It says:

(...)

%S Second with optional decimals (00..59 or 00.000000 .. 59.999999)

(...)

Does somebody know, how to activated the "optional decimals" via the %S parameter ?

Regards
Hendrix

Windows printing rounds OLE dates to full seconds. You must use Zorro functions, like dataParse() for reading and second() for printing decimals.

printf("%.3f",second(Date));

Hello Petra,

thank you for your help. Knowing your advise and reading the related part of the manual again, I found and understand the hint "rounds to full seconds".

Now using

string zeittext1 = strdate("%d.%m.%Y %a %H:%M",ldate(0,0) );
string zeittext2 = strf("%08.5f",second(ldate(0,0)));
file_append("Data\\ABC-LOG.txt",strf("\n%s:%s UTC ...",zeittext1,zeittext2,...), 0);

results in exactly what I need :

17.12.2021 Thu 12:45:02:43265 UTC ...
17.12.2021 Thu 12:45:09:62231 UTC ...

Regards
Hendrix
