Microsecond Time Utility

The `microseconds` package provides a utility to generate and parse timestamps with microsecond precision. It currently stands at version 0.2.0, with its last update occurring approximately six years ago (December 2019). This indicates that the package is no longer actively maintained. It intelligently adapts to the execution environment, utilizing `process.hrtime` for high-resolution timing in Node.js and `performance.now()` in browsers. If neither is available, it falls back to `Date.now() * 1000` for a lower-resolution microsecond timestamp. Key functionalities include `μs.now()` for current microsecond timestamps, `μs.parse()` to convert a microsecond value into a structured object or human-readable string, and `μs.since()` to calculate elapsed time. Due to its abandoned status, developers should consider more modern and actively maintained alternatives for critical applications requiring robust time precision.
