080901 - Zip File Operation Seems to Be Changing Date of Files
080902 - Pkzipc Switched Commands Apply Attribute Times Command Consistently
080903 - Backup Interim Transfers Between Computers Pkzip Configure Failing
080904 -
080905 - Follow up ref SDS 12 M65O, ref SDS 9 M65O.
080906 -
080907 - We have had problems the past few days transferring files between
080908 - computers with t11.bat and rcv.bat.  There have also been problems
080909 - with automatic backups, but they are more subtle, and so had not yet
080910 - sparked investigation, though curiosity was being aroused.
080912 -  ..
080913 - Decided today on converting commands to use the program pkzipc.exe,
080914 - received on 020903. ref SDS 3 FG4O  Command revisions for pkzipc were
080915 - discussed on 030203. ref SDS 12 N56F
080917 -  ..
080918 - Full conversion has been resisted to avoid time and frustration
080919 - learning a new command structure, and then changing a lot of code,
080920 - including figuring out where code has to be changed, and experimenting
080921 - to verify correct application, i.e., understand cause and effect,
080922 - within the meaning of "cognitive overhead," presented in NWO.
080923 - ref OF 15 LH6K
080925 -  ..
080926 - Now, however, time lost from extended transfers, and attempting to
080927 - configure pkzipc have risen to the level of encouraging investing time
080928 - to make improvements.
080930 -  ..
080931 - Pkzipc.exe commands do not have single character abbreviations
080932 - available in pkzip.exe.  The new command strings are therefore much
080933 - longer and so harder to remember and use.  Long command strings cause
080934 - mistakes and endless rework.  Correcting one mistake likely results in
080935 - another mistake leading to endless cycles of correcting corrections,
080936 - described in NWO. ref OF 14 7495
080938 -  ..
080939 - Long strings do not work well in DOS batch files.  Implementing the
080940 - Windows XP Start command using cmd executables makes long command
080941 - strings in batch files more easily accommodated for SDS, beginning on
080942 - 030902. ref SDS 16 YO6J and citing research on 030109. ref SDS 11 0Q7O
080943 - Batch file ops to call Windows Start command are described in detail
080944 - on 030902. ref SDS 16 B44K
080946 -  ..
080947 - The main problem seems to be the pkzip "times" command, because pkzipc
080948 - does not seem to be holding configuration...
080949 -
080950 -                      -times=all
080951 -
080952 - ...also discussed on 030203. ref SDS 12 9G8J
080954 -  ..
080955 - When this command is not set, pkzip assigns the date of extraction to
080956 - the files being extracted.  Therefore, eventually every file winds up
080957 - with the same date, and is continually transferred and backed up.  It
080958 - is a mess.  Just contemplating this problem causes a headache.
080960 -  ..
080961 - Design objectives are backing up only new and changed "work" files,
080962 - since everything else can be restored from permanent storage,
080963 - explained on 021012. ref SDS 5 5A41
080964 -
080965 -    The code in 03101 and backup.bat is designed to enter and preserve
080966 -    the date of the last interim backup, and backup everything from the
080967 -    prior date. ref SDS 5 1S9H
080969 -     ..
080970 -    Therefore, if a backup occurred yesterday, or several days earlier,
080971 -    the current interim backup should get everything from the prior
080972 -    date.  Normally, this is only a few MB.  Even if 5 MB is backed up
080973 -    for 60 days, this is only 300 MB, not 1 GB.
080975 -  ..
080976 - Clues about a problem began when a 50 file 40 MB set of pictures from
080977 - Mil's recent birthday party on 060121 kept scrolling across the screen
080978 - during transfers between computers.  The system is designed to avoid
080979 - multiple iterations.  Normally, things scroll so quickly across the
080980 - screen, that such errors are not noticed, but the size of the transfer
080981 - with everything in a constant format permitted notice of repetitive
080982 - error.
080984 -  ..
080985 - Processing the same data over and over, significantly extended the
080986 - time of transfers and daily backups.
080988 -  ..
080989 - Switching to pkzipc permits using -times=all with every extraction,
080990 - and so hopefully will solve the problem.  We can also enter an
080991 - attribute command to include "archive" and "hidden" that affirmatively
080992 - solves the problem of not transferring changed files.
080994 -  ..
080995 - Another big clue that pkzipc was not working correctly was that
080996 - maintenance on SDS macro files in...
080997 -
080998 -                       c: sd 03 0
080999 -
081000 - ...kept showing files that had not been modified suddenly had the
081001 - current date, and so were being continually reprocessed.  This
081002 - eperience had the suspicion of a virus continually changing program
081003 - files.  Investigation found no virus, but the problem continued.  It
081004 - was caused by failure of -times=all in transfers that continually
081005 - assigned the transfer date, so the dates and times were always out os
081006 - sync, and this grew more pronounced as more macros were modified over
081007 - several weeks.
081009 -  ..
081010 - Another problem occurred when SDS records were not being transferred.
081011 - Investigation showed that pkzip was not hold the configuration to
081012 - transfer files with an archive bit.  Investigation wound up showing
081013 - that we have been constructing bigger and bigger interim backups,
081014 - because with -times-all command failing, pkzip was assigning the
081015 - current date to every file transferred.  Interim backups for just 60
081016 - days are now about 1 GB, when they should be perhaps 50 MB.

081029 - Date Command Pkzipc Applies Date Format from Windows XP
081030 -
081031 - Turned out that switching from pkzip.exe to pkzipc.exe caused a
081032 - problem of date formats.  Pkzip.exe uses a consistent date format of
081033 - mmddyyyy.  This was a feature we needed to handle a 4 place year
081034 - representation.  However, pkzipc.exe uses the date format assigned to
081035 - the computer by the operating system.  So, to apply the date
081036 - consistently we need to have a common format for all computers.  Below,
081037 - research found how to set the date format in Windows XP. ref SDS 0
