4. What is the timezone settings? 

system\ControlSet001\Control\TimeZoneInformation> lsval
"Bias"=dword:00000168
"StandardName"="Central Standard Time"
"StandardBias"=dword:00000000
"StandardStart"=hex(3):00,00,0a,00,05,00,02,00,00,00,00,00,00,00,00,00
"DaylightName"="Central Daylight Time"
"DaylightBias"=dword:ffffffc4
"DaylightStart"=hex(3):00,00,04,00,01,00,02,00,00,00,00,00,00,00,00,00
"ActiveTimeBias"=dword:0000012c
  • Les clés “Bias” et “ActiveTimeBias” ont pour unités la minute:
BIAS:
# echo 'ibase=16;168' | bc
360 <=> 6 heures
ActiveTimeBias:
# echo 'ibase=16;12C' | bc
300 <=> 5 heures
  • Les clés “StandardStart” et “DaylightStart” sont à convertir comme suit:

Elles devraient correspondre à la structure SYSTEMTIME,mais il y a un décalage.
Exemple: 

"DaylightStart"=hex(3):00,00,04,00,01,00,02,00,00,00,00,00,00,00,00,00
00 = ?
00 = year
04 = mois, Avril
00 = Jour de la semaine, Dimanche=0
01 = Première semaine, 05 étant la dernière
00 = ?
02 = Heure, 2 Heure du matin
00 = Minute
00 = Sec
00 = ms
  • La clé DaylightBias se calcule comme suit:
1) # echo 'ibase=16;obase=2;FFFFFFC4' | bc
11111111111111111111111111000100

2) Le bit de poids fort étant à 1, la valeur de cette clef sera négative. On inverse les bits:
                          111011
                          
3) On ajoute 1 à cette valeur:
111011+1=00111100
en decimal:
-60
Si la valeur était positive, on n'aurait pas eu besoin de rajouter 1.
