Hi, i'm trying to decode MMS message.
Almost clear with all header fields, not with EXPIRY and Delivery-Time field.

Reading in WAP-209:
7.2.7. Delivery-Time field
Delivery-time-value = Value-length (Absolute-token Date-value | Relative-token Delta-seconds-value)
Absolute-token = <Octet 128>
Relative-token = <Octet 129>
7.2.10. Expiry field
Expiry-value = Value-length (Absolute-token Date-value | Relative-token Delta-seconds-value)
Absolute-token = <Octet 128>
Relative-token = <Octet 129>

And I still don't understand how to decode.
For ex. header

8C 80 - Message-Type: m-send-req
98 31 31 34 32 37 39 38 31 37 37 2E 34 31 32 35 34 32 33 35 31 00 - Transaction-Id: 1142798177.412542351
8D 90 - MMS-version: 1.0
97 11 EA 31 37 31 35 36 2F 54 59 50 3D 50 4C 4D EE 00 - To: 17156/TYPE=PLMN
96 10 EA 74 C3 A4 6D C3 A4 20 66 69 6E 6C 61 6E 64 00 - Subject: tämä finland (also have a question - subject is written in finnish. Do i need some actions to decode it? I mean 74 C3 A4 6D C3 A4)
88 06 81 04 02 25 42 F0 - Expiry: ???? (May be 81 is 'BCC' field?)
86 80 - Delivery-Report: Yes
89 19 80 ... - From: value...

Am i right?
How to decode this Expiry field?
Thanks a lot
