Epoch Time Converter

This tool provides bidirectional epoch conversion for Node.js developers, enabling precise mapping between epoch timestamps and human-readable date strings. It supports both seconds and milliseconds as input units and outputs in UTC or local time. Common use cases include log normalization, event correlation, and scheduling scripts.
Conceptually, the tool interprets numeric epoch values or parses date strings, infers or uses explicit units, and builds a canonical representation on which conversions are performed. It formats results in ISO 8601/RFC 3339 strings or numeric epoch values in the chosen unit, preserving millisecond precision when requested.
Audience and value: developers, data engineers, and QA teams in Node.js ecosystems gain a reliable conversion reference that reduces errors, standardizes timestamp handling across services, and accelerates debugging and data processing workflows.
Core features include unit-aware input, bidirectional conversion, multiple output formats, and optional timezone handling; use cases include log timestamp normalization, cross-service event sequencing, and data ingestion pipelines.
