Why are all times displayed in UTC timezone?
All dates and times on HTPBE? are displayed in UTC (Coordinated Universal Time) for consistency, accuracy, and transparency. This is an intentional design choice to ensure everyone sees the same absolute time regardless of their location.
What is UTC?
UTC is the global time standard used worldwide. It’s equivalent to GMT (Greenwich Mean Time) and serves as the reference point for all timezones. Unlike local time, UTC never changes with daylight saving time or regional adjustments.
Why We Use UTC:
- Universal consistency: Everyone sees the exact same timestamp regardless of their location or timezone
- No timezone confusion: A document created “at 14:00” could mean different absolute times in New York vs Tokyo. UTC eliminates this ambiguity
- Technical accuracy: PDF files internally store timestamps in UTC. Displaying them in UTC preserves the original data without conversion errors
- International collaboration: When sharing results with people in different countries, UTC provides a common reference point
- Audit trail integrity: For legal and compliance purposes, UTC timestamps create unambiguous records
How to Convert UTC to Your Local Time:
If you need to know what time something was in your timezone:
- Google search: Type “14:00 UTC in [your timezone]” to get instant conversion
- Mental calculation: Add your UTC offset. For example, if you’re in New York (UTC-5), subtract 5 hours from UTC time
- Time converter tools: Many free online tools convert UTC to any timezone
Common UTC Offsets:
- New York: UTC-5 (or UTC-4 during daylight saving)
- London: UTC+0 (or UTC+1 during summer time)
- Paris/Berlin: UTC+1 (or UTC+2 during summer time)
- Dubai: UTC+4
- Singapore/Hong Kong: UTC+8
- Tokyo: UTC+9
- Sydney: UTC+10 (or UTC+11 during daylight saving)
What This Means for You:
When you see a timestamp like “12.02.2026 09:35:21 UTC” on HTPBE?:
- This is the absolute, universal time the event occurred
- It’s the same timestamp everyone else sees, regardless of their location
- You can convert it to your local time if needed, but the UTC value is the authoritative record
Example Scenario:
You upload a PDF at 3:00 PM in New York (UTC-5). The check date shows “20:00 UTC” because:
- 3:00 PM in New York = 15:00 in 12-hour format
- 15:00 - 5 hours offset = 20:00 UTC
Someone viewing the same result in Tokyo (UTC+9) also sees “20:00 UTC”, not their local time. This ensures consistency and prevents confusion.
Bottom Line:
UTC display may seem unusual if you’re used to seeing local times, but it’s the professional standard for global systems. It ensures accuracy, eliminates timezone-related errors, and provides a reliable foundation for document fraud detection timestamps.

Verifying Specific Documents
You don’t have a copy to match it against, so you read the evidence inside the one PDF you were sent. A genuine file carries a consistent internal history: timestamps that line up, one clean revision layer, a producer fingerprint that fits the system that should have made it, an intact signature state if it was signed. An edited file breaks that consistency somewhere.
HTPBE? runs exactly this one-sided structural analysis and returns Intact, Modified, or Cannot Determine. It tells you whether the file was edited after it was generated — not whether the content is true, and not who sent it. Check whether a PDF is real →
A genuine bank statement is written directly by the bank’s core system, which leaves a distinctive structural signature. Re-save it through an editor or rebuild it in a spreadsheet and the file picks up a consumer-tool producer fingerprint and timestamps that drift apart — the mismatch HTPBE? flags as Modified.
The boundary: this checks the file, not the facts. It tells you whether the PDF was edited after the bank produced it. It does not confirm the account holder’s identity or that the balance is true — for that, pull the statement straight from the bank. See fake bank statement detection →
Reading Your Results
A creation date slightly after the check time usually means clock drift — a small difference between your computer’s clock and our server’s clock. Computers without automatic time synchronization can drift several minutes fast, so a PDF created on such a device will show a timestamp a few minutes ahead of the actual server time. This is completely normal.
Quick risk guide based on the time difference:
- Under 10 minutes: Low risk — almost certainly clock drift, not suspicious
- 10 minutes to 1 hour: Medium risk — worth investigating for important documents
- More than 1 hour: High risk — unlikely to be accidental; check independently
- Days, weeks, or months: Very high risk — strong indicator of intentional clock manipulation or metadata tampering
Always evaluate the full picture: the overall modification result, other metadata fields (Creator, Producer), and the context of where the document came from. A 4-minute discrepancy in a payment confirmation from a known client is routine. A 4-day discrepancy in a contract from a new counterparty requires investigation.
