/**
 * An exception type which automatically stores a standard stacktrace
 *
 * Usage:
 * On gcc and clang, linking against libstdc++exp (-lstdc++exp) is required and compiling with -g -Og and
 * linking with -lg is advised.
 *
 * `throw`ing an instance of `TracedError` (or types derived from it) will capture the stack trace.

//! A very basic utility to manage date and time in UTC timezone.
//!
//! Usage:
//!
//! ```zig
//! // The following examples assume that the current date and time is 25th May 1977, at 08:48 PM
//! const now = DateTime.now();
//! std.debug.print("{}\n", .{now}); // 1977-05-25 20:48:00
//! std.debug.print("{%d %B %Y at %I}:{%M %p}\n", .{ now, now }); // 25 May 1977 at 08:48 PM
//! // NOTE: the format string has to be split in two, because `:` is a special character in fmt
