-//
-// In previous versions of Zig, async/await used special keywords
-// like 'suspend', 'resume', and 'async' that operated on stackframes
-// directly. Those keywords no longer exist!
-//
-// Zig 0.16 replaced them with a unified I/O interface: std.Io.
-// This interface uses a VTable pattern - a struct of function pointers -
-// to abstract over different concurrency backends:
-//
-//   * Threaded  - classic thread-pool based I/O
-//   * Uring     - Linux io_uring
-//   * Kqueue    - BSD/macOS
-//   * Dispatch  - macOS Grand Central Dispatch
-//
-// The Io struct itself is tiny:
-//
-//     const Io = struct {
-//         userdata: ?*anyopaque,   // opaque state of the backend
-//         vtable: *const VTable,   // table of function pointers
-//     };
-//
-// Your code receives an Io value and calls methods on it.
-// The backend is chosen at initialization time - your code doesn't
-// need to know which one it is!
-//
-// In Zig 0.16, main() receives a std.process.Init struct to opt
-// into I/O and concurrency support:
-//
-//     pub fn main(init: std.process.Init) !void {
-//         const io = init.io;
-//         // ... use io ...
-//     }
-//
-// Let's start simple. Fix the main function to extract the Io
-// interface from init, then use it to get the current time.
-//
-const std = @import("std");
-
-pub fn main(init: std.process.Init) !void {
-    const io = init.???;
-
-    // Get the current wall-clock time using the Io interface.
-    // Hint: Timestamp.now() takes an Io and a Clock type (.real = wall clock).
-    const timestamp = std.Io.Timestamp.now(io, .real);
-
-    // Print the timestamp in seconds since the Unix epoch.
-    std.debug.print("Current time: {}s since epoch\n", .{timestamp.toSeconds()});
