question about GetBuffAura

[VesperCore]

I would like to know 3 things:
1: What is this "AuraStructUnk: 7", it's a byte that have value like 0-3-7-11 and maybe more.
2: How do you read AuraStructSpellEndTime ?
3: Do I miss any more data in this structure ?

AuraStructCreatorGuid: 1090FFFFFFFFFFFFFFFFFFFFFFFF033297 (128 bits GUID on PTR, this one if obviously edited)
AuraStructSpellId: 324
Name: Lightning Shield
AuraStructUnk: 7
AuraStructCount:5 (I had 5 stacks)
AuraStructCasterLevel: 90
AuraStructDuration: 3600000 (miliseconds = 1hour)

AuraStructSpellEndTime: 923749061
AuraStructSpellEndTime as double: 6.82238004931403E-314
AuraStructSpellEndTime as float: 8.540873E-06


for instance, this are the offsets I'm using for the structure :

    
            AuraStructCreatorGuid = 0x20, // read 16 bytes (GUID)
            AuraStructSpellId = AuraStructCreatorGuid + 16, // read 4 bytes (UINT)
            AuraStructUnk = AuraStructSpellId + 4, // read 1 byte, what is this ?
            AuraStructCount = AuraStructUnk + 1, // read 1 byte
            AuraStructCasterLevel = AuraStructCount + 1, // read 1 byte
            AuraStructDuration = AuraStructCasterLevel + 1,  // read 4 bytes
            AuraStructSpellEndTime = AuraStructDuration + 4, // read 4 bytes

About this unknown value (to me), here some samples:

AuraStructSpellId: 48266
Unk: 11

AuraStructSpellId: 122026
Unk: 3

AuraStructSpellId: 51915
Unk: 3

You must subtract the ReadUint(Timestamp) from ReadUint(AuraStructSpellEndTime) to get aura expires in miliseconds.

Thank you, do you know what are those unknowns 1byte? it seems to be one between casterLevel and duration too and one after SpellEndTime

            AuraStructCreatorGuid = 0x20, // read 16 bytes (GUID)
            AuraStructSpellId = AuraStructCreatorGuid + 16, // read 4 bytes (UINT)
            AuraStructUnk1 = AuraStructSpellId + 4, // read 1 byte, what is this ?
            AuraStructCount = AuraStructUnk1 + 1, // read 1 byte
            AuraStructCasterLevel = AuraStructCount + 1, // read 1 byte
            AuraStructUnk2 = AuraStructCasterLevel + 1, // read 1 byte, what is this ?
            AuraStructDuration = AuraStructUnk2 + 1,  // read 4 bytes
            AuraStructSpellEndTime = AuraStructDuration + 4, // read 4 bytes
            AuraStructUnk3 = AuraStructSpellEndTime + 4, // read 1 byte, what is this ?

These are the complete bytes for the "Lighning Shield" aura from +0 to +0x48

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 209 187 152 0 0 0 0 0 0 0 0 0 0 140 51 8 68 1 0 0 7 1 90 0 128 238 54 0 75 235 89 55 3 0 0 0 0 0 0 0

0x0 to 0x20: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (????)
0x20 to 0x30: 209 187 152 0 0 0 0 0 0 0 0 0 0 140 51 8 (GUID)
0x30 to 0x34: 68 1 0 0 (SpellID)
0x34 to 0x35: 7 (Unk1) ?
0x35 to 0x36: 1 (stacks)
0x36 to 0x37: 90 (CasterLevel)
0x37 to 0x38: 0 (Unk2) ?
0x38 to 0x3C: 128 238 54 0
0x3D to 0x40: 75 235 89 55
0x40 to 0x41: 3 (Unk3) ?
0x41 to 0x48: 0 0 0 0 0 0 0


Here my latest output:

[D] 08:29:52 - AuraCreatorGuid: 10901470643409114426144864410223033297
AuraSpellId: 324
AuraName: Lightning Shield
AuraUnk1: 7
AuraCount: 1
AuraCasterLevel: 90
AuraUnk2: 0
AuraDuration: 3600000
AuraSpellEndTime: 928639819
GetTime: 928189415
AuraTimeLeftInMs: 450404
AuraStructUnk3: 3

[Mr.Sergey]

I use the only data I need. Why should you know these bytes meaning if all the data already known?

Well, those bytes are data and are not knows;

0x34 is aura flags.
