Post by: hutch-- on August 17, 2022, 12:43:52 PM
Written into a normal Windows UI, a time stamp utility for setting file times.

See below for updated version.

Hi Hutch!

Selected LocalTime is 10 hour

SystemTime is 13 hour

but file is setted to 7 hour!!

-----------------------------

Selected SystemTime is 13 hour

but file is setted to 10 hour!!

Apparently "SystemTimeToFileTime" make a correction to local time, the correct function "LocalTimeToFileTime" doesn't exist.

Hi Hector,

It seems that the hour as set in the text box is not being converted correctly. I set the structure member as follows,

    rcall GetWindowText,hHour,pbuf,64
    mov rax, uval(pbuf)
    mov stm.wHour, ax

Then follow it with,

    invoke SystemTimeToFileTime,pstm,pftm
    rcall SleepEx,256,0                                 ; needs to have this delay
    invoke SetFileTime,hFile,pftm,pftm,pftm

Perhaps the API SystemTimeToFileTime is broken.

They just made that way, because they like these wanderings paths  :biggrin:

TzSpecificLocalTimeToSystemTime function must be used first:
Code: [Select]
  ; ---------------------------------------------

    mov hFile, flopen(pTxt)                             ; open file to modify

    invoke TzSpecificLocalTimeToSystemTime, NULL, pstm, pstml
    invoke SystemTimeToFileTime,pstml,pftm
    rcall SleepEx,256,0                                 ; needs to have this delay
    invoke SetFileTime,hFile,pftm,pftm,pftm

    invoke MessageBox,hWnd,LastError$(),pTxt,MB_OK      ; last error result

    flclose hFile                                       ; close file

With option GetSystemTime it works fine.

TzSpecificLocalTimeToSystemTime function must be used first:

This is only necessary with option GetLocalTime.
Strange that there is no hint in the documentation ...

Hi Greenhorn

SystemTimeToFileTime is converting values in boxes to local time (like if that values are UTC 0).

With option GetSystemTime it works fine.

Are you in UTC 0 (or at least your computer think that) ?


This is only necessary with option GetLocalTime.

I'm in UTC +2 (Central European Summer Time).

Hi Hector,

This line,

    invoke TzSpecificLocalTimeToSystemTime, NULL, pstm, pstm

Has done the job here, the hour as set in the text boxes ends up as the right time in the file listing in Winfile and Explorer.  :thumbsup:  :eusa_clap:  :biggrin:

Attached is the version with Hector's mod.
