High-Resolution Timestamps (present)

The `present` package, currently at version 1.0.0, provides a unified, cross-environment API for obtaining high-resolution timestamps. It is designed to work in both Node.js, where it leverages `process.hrtime`, and various browser environments, where it attempts to use `performance.now()` and its vendor-prefixed equivalents (`webkitNow`, `msNow`, `mozNow`, `oNow`). If no high-resolution API is available, it gracefully falls back to `Date.now()`. A key differentiator is its automatic polyfilling of `performance.now` in browsers upon script inclusion, though this behavior can be reverted using `present.noConflict()`. The package aims to offer consistent, precise timing for performance measurement or other time-sensitive operations across different JavaScript runtimes. Given its version and the nature of its dependencies (native APIs), it appears to be a stable, low-maintenance utility rather than one with frequent releases, typically publishing updates only when underlying platform APIs change significantly or critical bugs are identified.
