SetFTime() conversion error

[Badara Thiam]

Hello,

I am testing a xHarbour with FWH 8.6 application.
SetFTime() have a problem to return the time required :

*******************************************************
CLIPPER :

With Fivewin for Clipper , it make the time, but the seconds passed
to SetFTime() are not the seconds given to SetFTime() :

SetFTime( nIdent, "10:10:10", Date()) gives seconds * 2

file time is then "10:10:20".
*******************************************************
xHARBOUR :

With Fivewin for xHarbour , the hours and the seconds passed
to SetFTime() are not these given to SetFTime() :

SetFTime( nIdent, "10:10:10", Date()) gives hours + 2 and seconds - 2

file time is then "12:10:08".
*******************************************************
Tested with date franch format (DD/MM/YYYY)

Regards,

Badara,

The C conversion funtions that we use seem to be ok, so the error has to be in the Windows API (?)

test.prg

Code: Select all  Expand view  RUN

#include "FiveWin.ch"

function Main()

   local aTime := Test( "10:11:12" )

   MsgInfo( aTime[ 1 ] )
   MsgInfo( aTime[ 2 ] )
   MsgInfo( aTime[ 3 ] )

return nil

#pragma BEGINDUMP

#include <hbapi.h>

static unsigned int CharsToWord( char * pChars )
{
   unsigned int w = 0;

   if( pChars[ 0 ] != '0' )
      w = ( pChars[ 0 ] - '0' ) * 10;

   if( pChars[ 1 ] != '0' )
      w += ( pChars[ 1 ] - '0' );

   return w;
}

HB_FUNC( TEST )
{
   char * pTime = hb_parc( 1 );
   
   hb_reta( 3 );

   hb_stornl( CharsToWord( pTime ),     -1, 1 );
   hb_stornl( CharsToWord( pTime + 3 ), -1, 2 );
   hb_stornl( CharsToWord( pTime + 6 ), -1, 3 );
}   

#pragma ENDDUMP

Antonio,

After others tests i see that the seconds
in leee, with xHarbour, is not the fact of
SetFTime() but of Directory().
The hours in more is the fact of SetFTime().

Test please with hour between 0 and 1:59
like this :

- SetFTime(nIdent, "01:00:00", Date())
or
- Hour between 22:01 and 23:59
for the file time before use SetFTime()


I will test today on other PC on XP.
Yesterday it was on Vista Homel Premium.

Antonio,

The function SetFTime() have a vicious error !!!

She write the Date/time of GMT time, not local date/time
passed in parameters.

The difference is not 2 hours now, but 1 hour,
since the french time is in Winter time...

Regards.

Hello,

There is always a problem with SETFTIME() and SETFDATI() for [x]Harbour.
The date and time writted are not local date and time but GMT time.
In France there is different time in summer than in Winter.
This bug is a big problem for network. It is not possible to forget it...

Has someone solved this ?

Best regards.

[Badara Thiam]

I think i have found the problem, it was in my code.
I used DTOS() to pass the date parameter to SetFTime()
and you know the result...

Sorry, forget my last post please.

Best Regards.

Dear Badara,

I think i have found the problem, it was in my code.
I used DTOS() to pass the date parameter to SetFTime()

I too have have the problem that the Time is GMT, so it's different when you look at the file with DIRECTORY (or just with a DIR from the Command Prompt)

Could you please explain me how you did solve it ?

Thanks,
Davide

Hello

See below the actual state of my function SETFDATI(). You can see here where was the problem.
I don't give functions used in SETFDATI() like HEURES() who give the space time between two times in "C" type,
and HEURESADD() who add hours, minutes and seconds in "C" type also.

Dear Badara,

thank you.
I finally found out that GetFTime() retrieves the same date/time of SetFTime(), so I solved my problem that way.
To retrieve the difference in hours (GMT+/-) you can just compare the result of Directory() with GetFTime()

Thanks again,
Davide
