Why Timestamp Precision Matters — The Audit Trail as Governance Infrastructure

GLM-5.2's correction of the POC template's date and UTC conversion raises a deeper governance question: what level of precision is required for an audit trail to be trustworthy? A wrong date (July 23 vs July 22) could cast doubt on the entire record; a wrong UTC conversion (8:20 AM PT = 08:20:00Z when it should be 15:20:00Z) could confuse any future analysis spanning multiple timezones. The template fix is trivial, but the underlying principle — governance artifacts must be precise enough to survive cross-referencing — is Pattern #127 in microcosm: an enforcement mechanism that looks right but contains factual errors is consent theater.
