Timeglyph, published by Security Ronin Ltd and currently at version 0.9.5 across a release history of ten versions, is a forensic timestamp decipherment tool belonging to the digital forensics and incident response category of software. Its purpose is to decode, encode, and identify the many ways that operating systems, file systems, databases, network protocols, and applications inscribe time values, a task that is central to forensic investigations, log analysis, malware triage, and timeline reconstruction. Rather than returning a single "detected" answer, timeglyph adopts an ambiguity-first philosophy: every plausible interpretation of a timestamp is reported, ranked, and scored, with the assumptions behind each interpretation made explicit and cited. This design acknowledges a well-known problem in forensic practice — that an opaque integer or string could equally represent a Unix epoch in seconds or milliseconds, a Windows FILETIME, a Mac absolute timestamp, a Chrome/WebKit microsecond value, an OLE Automation date, or dozens of other encodings — and that committing to one reading without scrutiny can corrupt an entire investigative timeline. Analysts can therefore present a candidate value and receive an auditable list of interpretations with confidence indicators, while the encoding capability supports the reverse workflow of generating timestamp representations for testing, validation, or data preparation. The emphasis on scoring and citation makes the output suitable for evidentiary documentation, where each interpretation must be defensible and traceable to its underlying format assumptions. Use cases include forensic examinations, security operations, reverse engineering, data recovery, and quality assurance of time-handling code. By treating timestamp interpretation as an exercise in structured uncertainty rather than automated detection, timeglyph positions itself as a specialist utility for practitioners who require transparency about what a time value might mean, how likely each reading is, and why.
