In PREA investigations, how should timestamps be treated?

• A. Timestamps are optional.
• B. Document timestamps for all evidence.
• C. Destroy timestamps to protect privacy.
• D. Timestamps apply only to digital evidence.

Answer: (B)

In PREA investigations, recording timestamps for every piece of evidence is essential to establish the exact sequence of events and preserve the investigation’s integrity. Timestamps create a verifiable timeline that shows when reports are made, interviews occur, evidence is collected, and items are created or altered. This timing information supports credibility by helping to align statements with what actually happened and by demonstrating a clear chain of custody—who handled the evidence and when. Because of this, timestamps should be documented for all evidence, not left out or treated as optional.

It’s not correct to treat timestamps as optional, nor to destroy or obscure them. Timestamps are important for both physical and digital evidence, and they should be captured consistently across the board. A practical approach is to record the date and time to the nearest minute in a standardized format and time zone, noting who recorded it and where it was recorded. If clocks conflict, document the discrepancy and reference the facility’s standard time as the basis, then note any known offsets.

In short, thorough, consistent timestamping for all evidence strengthens the timeline, supports authenticity, and helps ensure a fair, traceable investigation.
