Date and Time Formatting with strftime

strftime is a JavaScript utility library that provides `strftime`-style date and time formatting, mimicking the functionality found in C's `strftime` function and Ruby's extensions. The current stable version is `0.10.3`, primarily receiving maintenance updates and bug fixes rather than active feature development. This is indicated by its infrequent release cadence since 2016's planned v1.0 release that never materialized. Key differentiators include its support for various format specifiers (including Ruby extensions), robust localization capabilities through custom locale objects or bundled identifiers, and timezone handling via offsets. It is designed to work both in Node.js environments and web browsers, offering a consistent API for formatting `Date` objects into human-readable strings. The library aims for broad compatibility, even supporting very old Node.js versions.
