Format for timestamps
In this article, we show how timestamps are stored and displayed to users in the frontend.
All timestamps in Playbook are stored in UTC (Universal Time Coordinated) based on the ISO 8601 standard.
That means we use a single, universal time format across all systems and regions. It prevents issues caused by daylight saving changes or local time differences and makes sure every event is traceable and consistent.
When Playbook creates a PDF automatically, we include the UTC timestamp to show exactly when the document was generated (signed, etc.) by the system. This makes the record reproducible and transparent, no matter where it’s viewed.
In the frontend, we display times in the user’s local timezone. The conversion follows RFC 3339, so the format remains compatible with ISO 8601. It’s purely a visual adjustment, the stored UTC value itself never changes.
