What it is

DE 7 is set when the message is transmitted and, unlike DE 12/13, is expressed in UTC. Together with DE 11 (STAN) and the acquirer/terminal identifiers it forms the practical matching key for responses, reversals, and duplicate detection.

Specification reference

Defined in ISO 8583:1987 (base). Card networks publish their own dialect tables (Visa BASE I / V.I.P., Mastercard CIS) that refine formats, lengths, and — for private-use elements — the entire layout. Always confirm against the interface specification you implement.
