utcTimeOffset

Validations ASN.1 Parent Types

All timestamps are in the local time of the Sender PMN.  So that the time can be equated to time in the Recipient PMN, the difference between local time and UTC time must be supplied.

Derivation: 

UTC Time Offset = Local Time minus UTC Time

Example:     Washington DC, USA  1000hrs  10/Oct/97

                        UTC Time                      1500hrs  10/Oct/97

                        UTC Time Offset = 10 - 15 = -5

 

                        Madrid, Spain                               1600hrs  10/Oct/97

                        UTC Time                      1500hrs  10/Oct/97

                        UTC Time Offset = 16 - 15 = +1

 

                        Sydney, Australia        0100hrs  11/Oct/97

                        UTC Time                      1500hrs  10/Oct/97

                        UTC Time Offset = (01 + 24) - 15 = +10

(note that where dates are different 24 hours are added to the time of the greater date)

Conditionality:

Mandatory within items

File Creation Timestamp

Transfer Cut Off Timestamp

File Available Timestamp

Mandatory within group UTC Time Offset Information.

Note that the HPMN needs the location and UTC Time Offset for each type of timestamp.  On a call level there might be more than one UTC Time Offset valid.
