You might notice that the timestamp shown in your signed document doesn’t exactly match the timestamp in the activity log.
Don’t worry — this is expected and completely normal.
🔍 Why this happens
The difference is caused by time zones.
Addo Sign stores all timestamps in UTC (Coordinated Universal Time) — the international time standard used across systems and time zones.
However, when timestamps are displayed (for example, in a PDF or in your browser), they’re often converted to your local time zone.
If you’re in Denmark, your local time is usually UTC+1 or UTC+2 (depending on daylight saving time).
🌍 Example
Location | Time zone used | Example |
Audit log | UTC (system time) | 2025-06-12 12:30 UTC |
Signed document | Danish local time (UTC+2) | 2025-06-12 14:30 (CEST) |
Both timestamps represent the same signing event, just shown in different time zones.
🧠 Why we use UTC
Using UTC ensures:
Consistency across users in different countries 🌎
Reliable audit trails for legal and compliance purposes 🧾
No confusion from daylight saving time changes ⏰
This approach is standard in secure digital signing systems.
✅ Summary
Addo Sign stores timestamps in UTC.
Danish time is UTC+1 in winter and UTC+2 in summer.
A 1–2 hour difference between the document and the log is expected.
Both timestamps refer to the same event — only shown in different time zones.
💡Tip: If you ever need to compare times: Local time = UTC time + time zone difference
Example: 12:30 UTC → 14:30 Danish summer time (UTC+2)
