Bonjour,

En TCL, vous pouvez utiliser la commande "clock format" pour convertir votre date format unix en date plus lisible.

La syntaxe est :
clock format variable -format %
où % va indiquer le type d'affichage de la date que vous souhaitez.

Par exemple :
set var [file mtime fichier.xxx]   <--  extrait la date du fichier "fichier.xxx" au format Unix
set  var2 [clock format $var -format %D]  <-- convertit la date au format %D c'est à dire MM/DD/YY
puts $var2  <--  affiche le résultat

Vous souhaitez un affichage de type JJMMAAAA, vous devez donc utiliser %d%m%Y ce qui donne dans notre exemple :
set  var2 [clock format $var -format %d%m%Y]

Vous pouvez extraire bien d'autres formats/informations :

%a     Abbreviated weekday name (Mon, Tue, etc.).
%A    Full weekday name (Monday, Tuesday, etc.).
%b    Abbreviated month name (Jan, Feb, etc.).
%B    Full month name.
%c    Locale specific date and time. The format for date and time in the default "C" locale on Unix/Mac is "%a %b %d %H:%M:%S %Y". On Windows, this value is the locale specific long date and time, as specified in the Regional Options control panel settings.
%C    First two digits of the four-digit year (19 or 20).
%d    Day of month (01 - 31).
%D    Date as %m/%d/%y.
%e    Day of month (1 - 31), no leading zeros.
%g    The ISO8601 year number corresponding to the ISO8601 week (%V), expressed as a two-digit year-of-the-century, with leading zero if necessary.
%G    The ISO8601 year number corresponding to the ISO8601 week (%V), expressed as a four-digit number.
%h    Abbreviated month name.
%H    Hour in 24-hour format (00 - 23).
%I    Hour in 12-hour format (01 - 12).
%j    Day of year (001 - 366).
%k    Hour in 24-hour format, without leading zeros (0 - 23).
%l    Hour in 12-hour format, without leading zeros (1 - 12).
%m    Month number (01 - 12).
%M    Minute (00 - 59).
%n    Insert a newline.
%p    AM/PM indicator.
%r    Time in a locale-specific "meridian" format. The "meridian" format in the default "C" locale is "%I:%M:%S %p".
%R    Time as %H:%M.
%s    Count of seconds since the epoch, expressed as a decimal integer.
%S    Seconds (00 - 59).
%t    Insert a tab.
%T    Time as %H:%M:%S.
%u    Weekday number (Monday = 1, Sunday = 7).
%U    Week of year (00 - 52), Sunday is the first day of the week.
%V    Week of year according to ISO-8601 rules. Week 1 of a given year is the week containing 4 January.
%w    Weekday number (Sunday = 0, Saturday = 6).
%W    Week of year (00 - 52), Monday is the first day of the week.
%x    Locale specific date format. The format for a date in the default "C" locale for Unix/Mac is "%m/%d/%y". On Windows, this value is the locale specific short date format, as specified in the Regional Options control panel settings.
%X    Locale specific 24-hour time format. The format for a 24-hour time in the default "C" locale for Unix/Mac is "%H:%M:%S". On Windows, this value is the locale specific time format, as specified in the Regional Options control panel settings.
%y    Year without century (00 - 99).
%Y    Year with century (e.g. 1990)
%Z    Time zone name.
