I am finding that directoryEntryDate returns a different timestamp in 6.30 than 6.20. Is there a reason this might be possible?

Knowing I would get complaints without sample source code so I made up this one from the big program. I left the essence of the whole loop because that's just I how I am using it.

Code: Select all

     enableexplicit

     declare justScanDirectory ( dirName.s )

     global.i hFile
     hFile = openFile ( #pb_any, "t_filedates.txt", #pb_file_append )
     justScanDirectory ( "i:\library3" )
     closeFile ( hFile )

     procedure justScanDirectory ( dirName.s )
          protected.i hEDir, fSize, fDate
          protected.s fName

          hEDir = examineDirectory ( #pb_any, dirName, "*.*" )
          while nextDirectoryEntry ( hEDir )
               fName = directoryEntryName ( hEDir  )
               fsize = directoryEntrySize ( hEDir )
               fdate = directoryEntryDate ( hEDir, #pb_date_modified )

               if fName = "." or fName = ".."
                    continue
               endIf

               select directoryEntryType ( hEDir )
                    case #pb_directoryEntry_File
                         writeStringN  ( hFile, str ( #pb_compiler_version ) + "   " + fName + " | " + str ( fsize ) + " |  " + formatDate ( "%yyyy-%mm-%dd %hh:%ii:%ss", fdate )  + " |  " + str ( fdate ) )

                    case #pb_directoryEntry_Directory
                         justScanDirectory ( dirName + "\" + fName )

               endSelect
          wend
     endProcedure

I'm sorry but I don't use the IDE editor. I used this batch file to compile it:

Code: Select all

del t_filedates.txt
set c2=t_filedates
call "\progutil\pureBasic\pureBasic 6.20\compilers\pbCompiler.exe" "%c2%.pb" --output "%c2%.exe" --optimizer /XP --thread  /dynamiccpu /ADMINISTRATOR
t_filedates
call "\progutil\pureBasic\pureBasic 6.30\compilers\pbCompiler.exe" "%c2%.pb" --output "%c2%.exe" --optimizer /XP --thread  /dynamiccpu /ADMINISTRATOR
t_filedates
v t_filedates.txt

And these are the results filtered for one particular file:

Code: Select all

620   Instrumental.mp3 | 4262603 |  2013-08-11 16:37:44 |  1376239064
630   Instrumental.mp3 | 4262603 |  2013-08-11 17:37:44 |  1376242664

So what Windows have to say about that file:

Code: Select all

Sun 08-11-2013  04:37 pm         4,262,603 Instrumental.mp3

I'm only showing one file for brevity but it happens on many files.

I did see a viewtopic.php?p=637152&hilit=directoryEntryDate#p637152 but I don't think it applies here. And for reference, I'm United States Central Time which I think +6 UTC.

Any thoughts or ideas would be appreciated.

Addendum:

I added getFileDate ( ) to see if the outcome was different. Not sure I'm using that right but getFileDate returned the same time as directoryEntryDate ( )

Code: Select all

     gdate = getFileDate ( dirName + "\" + fName, #pb_date_modified )

Code: Select all

     writeStringN  ( hFile, prefix + fName + " | " + str ( fsize ) + " | directoryEntryDate > " + formatDate ( "%yyyy-%mm-%dd %hh:%ii:%ss", fdate )  + " | getFileDate > " + formatDate ( "%yyyy-%mm-%dd %hh:%ii:%ss", gdate )  )

Addendum:

Now I understand! I just changed my time to July 31, 2026 and now the times reported are the same.

Code: Select all

620   Instrumental.mp3 | 4262603 | directoryEntryDate > 2013-08-11 17:37:44 | getFileDate > 2013-08-11 17:37:44
630   Instrumental.mp3 | 4262603 | directoryEntryDate > 2013-08-11 17:37:44 | getFileDate > 2013-08-11 17:37:44

Okay, the directory is reporting a different timestamp depending on (I'm guessing) whether Daylight Savings Time is in effect! Here is a condensed version from my command prompt showing the directory after I had changed the time.

Code: Select all

I:\library3 > echo %time% %date%
17:11:01.53 Fri 07-31-2026

I:\library3 > dir *.mp3
Sun 08-11-2013  05:37 pm         4,262,603 Instrumental.mp3

I:\library3 > echo %time% %date%
17:11:23.51 Sat 01-31-2026

I:\library3 > dir *.mp3
Sun 08-11-2013  04:37 pm         4,262,603 Instrumental.mp3

I:\library3 >

Is 6.30 is handling DST differently ?

Addendum: I am working with two things.

First, I'm trying out getFileAttributesEx_ to get \ftLastWriteTime which is a quad UTC value. And then and using various posts in the past convert that to a PureBasic time using (PeekQ(@fileData\ftLastWriteTime) - #WIN32_FILE_TIME_OFFSET) / 10000000 I can use that for the definitive "has the timestamp changed"

Next, when I need to display it, I have to convert to local time using FileTimeToLocalFileTime_ ( ). I think I've got a function for that working.

Still, it's curious about PB 6.20 and 6.30, but I think I have a solution.
